Bike Frame Materials Explained

Impacting important characteristics such as ride quality and feel, a frame is often the defining feature of your favorite bike. So regardless of whether you’re getting stuck into a dream bike build, considering a new ride or are just a sucker for the technical detail, we’ve put together this handy guide to help you better understand the foundation of your bicycle.


Often referred to as the heart of a bike, a frame can be made from either carbon fiber, aluminum, titanium, steel or a combination of these materials. Each bicycle frame material offers a list of differing characteristics that will affect the cost, comfort, weight, stiffness, strength and durability.


It’s worth noting that it’s often how the chosen material is used by the engineers and manufacturers that matters most, and this is something that each brand will typically play with. Before we jump into the details, it’s worth considering the following factors when deciding what material is best for you;


  • Weight: Your bike needs to be strong enough to carry you and any extra luggage you plan on carrying in the form of panniers, racks or mounts. Each material will have different strength properties, fatigue rates and impact resistance but there is always a trade-off between weight and durability. Another aspect of weight to consider is how important having a lightweight bike is to you. For example, if you’re chasing performance advantages than having a light weight bike would be higher on your list.


  • The Purpose of The Bike: If you plan on racing then a stiff, lightweight bike is the ideal choice, narrowing the type of materials to choose from. Conversely, if you are touring or planning a riding adventure that requires long hours in the saddle and the ability to carry items, then durability is the priority and again, narrows the type of material to choose from.


  • The Area You Ride: It may not be apparent that your postcode could influence the type of material your bike is built from, but consider a material like steel that will rust in wet, humid climates. A material like aluminum might be a better choice given the conditions while still providing similar characteristics to steel.


  • How Long You Plan On Having The Bike: All materials will fatigue over time but some faster than others. Steel will rust if not taken care of but is more durable than aluminum over the long term. Carbon fiber and titanium frames have exceptionally high fatigue rates meaning they will last and last and last.


  • Your Budget: Budget is often the biggest factor in choosing a bike and consequently its material. As a generalization, in order of most expensive to least expensive, titanium takes the cake, followed by carbon fiber, aluminum and steel. As always, the tradeoff between what you are willing to spend for what outcome is the key consideration.


To help provide more clarity on the various bike frame materials available, we’ve summarized each material type, its properties, characteristics and more importantly how they translate into ride quality. But, today I only introduce the material part of steel. For more details about other materials, please click here: Bike Exchange




Ah steel, the no fuss workhorse of bike frame materials. Steel was the universal choice of racing bike frames until aluminum appeared in the 1970’s and 1980’s and carbon fiber took over in the 1990’s.


There are two distinct types of steel used in the bicycle industry. The first is high tensile, or otherwise known as ‘Hi-Ten’, this is a cheaper grade steel commonly found in cheaper bikes, especially those from department stores. It offers an incredibility poor strength-weight ratio and so manufacturers will typically use this material in order to hit low price points. By comparison, higher-end steel bikes are likely to use chromoly, or CroMo for short (generally short for chrome molybdenum) steel, which as an alloyed steel offers superior strength properties to Hi-Ten and so can be butted and made thinner/lighter.


Steel is inexpensive, exceptionally durable, highly resistant to fatigue, easily repaired and easy to work with. Unlike carbon fiber and aluminum, damage to a steel bicycle frame is typically easily repaired. Somewhat surprisingly despite its strength, steel offers good levels of compliance thanks to its elastic properties. The downside of steel is that it is prone to oxidization (rust) and carries a weight penalty over other materials.


Touring and adventure bikes are commonly made from steel thanks to the exceptional durability and strength on offer. This enables riders to carry large amounts of luggage without compromising the bikes performance. Steel also features heavily on entry level and recreational bikes where weight isn’t such an important factor.


  • Pros of Steel: Cost and ease to manufacture, strength, durability.


  • Cons of Steel: Weight, corrosion resistance.


How It’s Made


Joining steel tubes together involves similar welding processes to aluminum frames, but further options exist including ‘Brazing’ and the use of lugs. Brazing is similar to TIG welding but uses a ‘filler’ material that is melted and used to join the tubes. The filler material is commonly silver or brass but could be a myriad of other alloys too. Lugs act as connectors at junction points of the frame, creating a sleeve for the tubes to slide into. Prior to constructing the frame, the ends of the steel tubes are precisely cut to fit perfectly into the lugs and brazed together. The use of lugs creates an immensely strong joint, and being an older manufacturing technique carries a side perk of giving a bike a ‘classic’ look.


Steel bicycle frames are perhaps the easiest frames to repair due to the availability of the equipment and supplies, as well as the material’s resistance to repeated heat. For this reason, steel is a great option for commuters, recreational cyclists and touring riders that need a highly durable bike.


If you want to get more information about bike frames, I recommend that you can visit the website of Maxway Cycles Co., Ltd.: Maxway is a leading manufacturer of steel bicycle frames and other kinds of bike frames. The company has built up solid relationship with a lot of steel bicycle frame manufacturers in Taiwan who supply high quality steel bike frame, bicycle frame products at decent prices.

Tell You Some Simple Introduction of Pipe Fittings

The components used in a piping system to connect the various sections of the pipe in order to change the direction of flow, are called fittings. Fittings are made from a number of materials including steel, bronze, cast iron, plastic and glass.


Standards have been established to ensure that fittings are made from proper materials and are able to handle the designed pressures. Some of the important functions of these fittings are:


  • Changing the direction of flow


  • Providing branch connections


  • Changing the size of lines


  • Closing lines


  • Connecting lines.


Fittings for Changing The Direction of Flow


To change the direction of flow, the pipe fittings that are normally used are referred to as elbows. Elbows generally come in all angles but those that are commonly used are the 45° and 90° ones.


Fittings for Changing The Size of The Pipelines


The function of the reducer is to reduce the line to a smaller pipe size. One reason for doing so is to increase the pressure in the system.


Pipe Joints


Pipe joints can be of the screwed, flanged or welded type. Each of these joints which are widely used, have their own advantages and disadvantages.


Screwed fittings are joined to the pipe by means of threads. The main advantage of the threaded joints is that the pipe length can be easily tailored at a later stage. As a threaded joint has metal-to-metal contact between the threads of two mating parts of the pipe, the risk of leakage is high. Hence sealing of the threaded joint becomes very important. The traditional method of providing a seal between the mating threads is to coat the threads with a paste dope. In recent years, the invention of Teflon sealing tapes has made for a more effective solution. The Teflon (being a registered trademark of Du Pont De Neumors and Company) tape can be simply wound over the threads for sealing.


Flanged fittings are either forged or made as cast pipe fittings. A flange is a rim or ring at the end of the fitting, which mates with another section of the pipe. Pipe sections can also be made with flanged ends. Flanges are joined either by being bolted together or by being welded together. The flanged faces again have metal-to-metal contact and proper sealing needs to be provided between the two mating surfaces to avoid leakages. A gasket is usually inserted between the mating surfaces of two flanges, which are bolted together. Normally, compressed asbestos gaskets can be used under conditions of normal pressure and temperature. However, when the system operates under higher pressure and temperature conditions, higher-grade gaskets are used.


Other pipe fittings used in flanged connections include expansion joints and vibration dampeners. Expansion joints have three functions:


  1. They compensate for slight changes in the length of the pipes, by allowing the joined sections of rigid pipes to expand or contract with changes in temperature.


  1. They allow pipe motion either to the side or along the length of the pipe, as the pipe shifts after installation.


  1. They help dampen vibration to some extent and reduce the noise carried along the pipe and originating from distant pumps.


It has a leak proof tube that extends through the bore and forms the outside surface of the flanges. Natural or synthetic rubber compounds are used for this purpose, depending on the type of application. Other types of expansion joints include metal bellows (corrugated type), spiral wound types and slip joint types.


Vibration dampeners are designed specifically to absorb vibration because vibrations reduce the life of the pipes as well as the operating equipment. They also eliminate line noises carried by the pipes.

A Wonder in the Materials World: Stainless Steel Sheet

Material scientists have created stainless steel, the most versatile alloy which can be seen in its many applications because of its corrosion resistant properties


The introduction of a minimum of 12% chromium into the steel alloy renders it corrosion resistant. This resultant product is called stainless steel sheet. There are many grades according to the alloy content and they are named variously as austenitic, martensitic, ferritic, precipitation hardening, super and duplex alloys.


Popular Grades of Stainless Steel


Austenitic grades of alloys which are stainless and non-magnetic. These cannot be hardened by heat treatment. Commonly used austenitic alloys are iron-chromium-nickel steels. The common grades are the 300 series which are used for their stainless properties and unusually good mechanical properties. The basic grade of this series is the 304. The L grades of this series are the low carbon grades (as in 304l) which provide extra corrosion resistance after welding. The carbon content is kept at 0.03% or less to avoid carbide precipitation. Higher carbon content is useful when the metal is subjected to very high temperatures and has to retain its strength.


The two other popular grades in this series are 316 and 317


Martensitic Grades of Alloys which are corrosion resistant and amenable to hardening by heat treatment. These are chromium steels with no nickel content. They are magnetic. The most common grades in this are the basic 410 and 420, where 420 has increased carbon more than 410 to improve its mechanical properties


Ferritic Grades – Even more corrosive resistant than the martensitic grades, these are highly resistant to cracking due to stress related corrosion. These are also magnetic with only chromium and no nickel. They are considered inferior to austenitic grades, but superior to martensitic grades. 430 is the base grade, which is used commonly.


Physical Forms


They come in a variety of forms like coils, sheets, bars and plates




For its easy maintenance and corrosion resistant properties, stainless steel sheets find diverse applications in:


  1. Modern architecture


  1. Food processing industry


  1. Industrial uses, such as chemical and fuel tankers, chemical plants and petrochemical plants, pharmaceutical industries (for hygienic environment)


What are Stainless Steel Sheets Standards?


There are many world recognized standards of stainless steel sheets which categorize the stainless steel sheets into different grades as explained above. These may be voluntary grading agencies, country specific agencies or associations of steel producing companies in a particular country. Sometimes any grade of steel marketed by a company will mention different standards of grading having been applied to it.


How the Demand for Stainless Steel Plated is satisfied?


There are suppliers worldwide who have industry specific grades available for their customers. They have websites and can be contacted easily for further details through a ‘contact us’ webpage. They are also present in social media like Facebook and Twitter. It does not matter if the supplier is from another country in this era of globalization. There is not much difference in the way of doing business.


Future of the Stainless Steel Sheet Industry


Since stainless steel sheet is such a versatile material, there is ongoing research and more grades are added to the existing ones as they are developed and tested, having unique qualities and different applications


The invention and countless applications of stainless steel sheet is a real wonder in the materials world and the future of the steel industry is bright with companies worldwide engaged in supply of this wondrous alloy.

A New Market Flood? Stainless Steel Pipe?

Plumbing has come a long way in the last 2,000 years. Yes, Ancient Romans are famous for their aqueducts, surely one of mankind’s greatest inventions, but what we must also remember is that those same Romans were the first civilization to transport water with the use of lead, a toxin. Now, as it turns out, the Romans lucked out by having high calcium content in their drinking water, which coated their pipes and kept them safe (the same could not be said about their lead cookware, unfortunately).

Since that time, humans have gone through many different materials to convey their water. Wood was used in Britain and Early America, for example. Concrete has been used, a material that Romans would have approved of. In modern America, copper has long been the choice, but with the ever-rising cost of copper that may be finally changing.

Enter stainless steel, an American classic.

More and more, homeowners, businesses, and contractors alike are heading to steel pipe supply companies for their water conveyance needs. Surprisingly, they cite cost, among many other things, as one of their main reasons for changing. Stainless steel pipe prices may not be the same as copper, but as any contractor will tell you, many factors go into the final cost of a product.

First off, steel pipe is lighter than copper, so transporting it is cheaper. The initial savings here may be minimal, but for contractors who make repeated trips to steel pipe supply companies, this means big savings. Contractors will also be quick to note that stainless steel pipe is less likely to be stolen by worksite thieves, who have become a real nuisance to anyone installing copper in the last decade or so.

Home and business owners will also be happy to know that stainless steel pipe prices also lessen over the long term, for many reasons. Stainless steel pipes require no coating, yet it resists both internal and external corrosion, meaning that it will last longer and require fewer repairs and replacements.

Stainless steel’s sturdiness also means that it can be laid over longer stretches than copper, a benefit of particular interest to owners of larger buildings. Longer pipes mean fewer connections, and fewer connections mean less leaking and less overall maintenance.

Stainless steel also has a lower coefficient of friction, meaning it yields higher water pressure at the point of use and is safer for drinking, with any leaching chemicals well below recommended limits.

And if these cost-reducing and health factors aren’t enough, business and home owners will be happy to know that stainless steel is completely recyclable material. After its use, or if a piece needs to be replaced, the old pipe may be sold to recoup some of its original cost.

Whether stainless steel pipes will begin flooding the market in the years to come is yet to be seen. However, one thing is certain: for copper, the pressure is on.
