Guide to Roll Forming

Roll forming is a high-speed, high volume production process, which uses a roll forming machine to convert metal sheets or coils into parts as the metal moves through the machine. As the material passes through the machine, rolls situated on both the top and bottom of the machine apply pressure to bend the material thus forming various configurations. Roll forming is a metal roll forming process that is suitable in the fabrication of stainless steel, copper, aluminum and steel products.

Manufacturers use roll forming to create standard parts that include angles, rings, channels and other forms. Some manufacturers can also provide custom roll forming. Many industries rely on roll forming services to fabricate products, which can be utilized in rail cars, door frames and helicopter blades. The advantages of using roll forming services to create these parts are quick and efficient accommodation of high volume orders, diverse range of shapes created with this process and greater uniformity/ consistency of parts.

Corrugated Metal Roofing

Corrugated metal roofing has been in use since ages to cover factories, outhouses and barns, and has always been considered merely functional as well as ugly to look at. However, these days, people are looking at those early outhouses and barns with their corrugated metal roofing with a new mindset and are discovering that they do have a certain aesthetic appeal. Therefore, corrugated metal roofing is growing in popularity with people finding innovative ways to use it to beautify the roofs of their homes.

Corrugated Metal Roofing 

Needless to say that the corrugated metal roofing available these days are nothing like the ones that were used in the past. They have been modernized to suit today’s styles in housing. Advances in technology has made it possible to treat and coat them to prevent them from wearing out or rusting, thus making them long lasting and able to withstand the elements. New types of materials, which are being produced these days, make them far more durable compared to other roofing materials. Some of the types of corrugated metal roofing available these days include aluminum, galvanized steel, metal with naturally oxidized finishing, steel or aluminum with pre-painted finishes, and so on.

As its very name describes it, corrugated metal roofing is made up of alternating parallel ridges and grooves. Each sheet of metal has a wavy pattern akin to corrugated cardboard, serving the same purpose, of being strong while also remaining relatively lightweight. For instance, if you use a double layer of roofing material made of metal, not only would it weigh double but would also be doubly costlier compared to corrugated metal roofing, which would provide the same durability and strength, without the additional expense.

These days, with lighter buildings coming up, it has become essential to use lightweight roofing material, because heavyweight roofing can put inordinate strain and stress on structures, with the potential of damaging and degrading the supports of the house comparatively faster. Apart from corrugated metal roofing being less stressful for your house, it is also able to withstand the effects of inclement weather far better compared to other types of roofing.

Aside from protecting your home actively against severe weather conditions, corrugated metal roofing will also reduce your energy bill quite substantially, by keeping the heat in during the winter. This is mainly because, being so lightweight, it permits you to install additional insulation under the corrugated metal sheets.

The technique used for installing corrugated metal roofing is one of the main reasons that it is able to resist the most inclement of weather conditions such as tornadoes and hurricanes. It will hold out against almost everything, and rarely does it develop weaknesses or faults, hence it has the potential of keeping on protecting your house for even a lifetime. Plus, it will not show any wear and tear, continuing to look almost as good as new even years later, which makes it a sound and wise investment.

Galvanized Steel Roofing

Galvanized steel roofing is very popular, due to its toughness and durability. Read on to know more about this roofing material

It is a common fact that roofing is one of the vital parts of any construction. So, it must be made of materials that are strong and durable. Even the looks of the construction depends to some extent, on the type of the roofing material and so, you must choose the right type. There are many different types of roofing materials that are made of metals, fiberglass, asphalt, plastic, etc. This article will provide you with some information about galvanized steel roofing.

Galvanized Steel Roofing

What is Galvanized Steel Roofing
The concept of metal roofing was introduced in the latter half of the nineteenth century. Soon, it became so popular that these products were used extensively, for industrial, agricultural and even commercial purposes. However, the use of metal roofing declined gradually, as it was prone to rust and certain other problems. But, now these problems are overcome with advanced technology. At present, there are several varieties of metal roofing in the market and those made with steel are one of the popular types. Even in case of steel roofing, there are various versions, like, stainless steel roofing, corrugated types, galvanized steel roofing, etc. Let us look at what is galvanized steel and what are its features.

Galvanization is a process, in which metals like, iron, steel or aluminum, is coated with zinc. To be more precise, the metal (to be galvanized) is passed through molten zinc, at a temperature of 460°C, so that it reacts with zinc and forms a zinc carbonate on the surfaces. The inner layers contain both zinc and metal and the innermost is pure metal. Through galvanization, the metal is made free of rust and corrosion. Galvanization provides a protective covering for the inner metal. Even though metals like aluminum are used for galvanizing, it is galvanized steel that is found to be more popular and this is due to the heavier weight and durability of the latter. So, use of galvanized steel is mostly found in outdoor constructions. While this type of steel is used to make nails, beams, screws, etc. galvanized roofing sheets are very popular for roofing and siding purposes.

Galvanized Steel Roofing - Pros and Cons
As mentioned above, galvanized steel roofs are those roofing materials that are made of steel, but have undergone galvanization. This type of steel roofing material is available in different forms like, tile sheets, composite panels, corrugated roofing sheets, steel roofing shingles, etc. Galvanized steel roofing is tough and durable. It is also resistant to rust and corrosion. This roofing material is said to withstand storm, hail, snow, etc. It is also fire resistant. Being lightweight, galvanized steel roofing is easy to install. If you have speculations about its resistance to hailstorms, you may go for galvanized steel with heavy gauges and high qualities. This roofing, when painted in light shades, can also reduce your cooling costs, as it can reflect heat. However, plain galvanized steel roofing has a silvery surface that shines and this may result in glares and reflections that may be annoying for many. In case of corrugated galvanized steel roof, some people prefer pouring concrete over the roofing, so as to make it strong. Even the reflection problem will not arise in such cases. As compared to stainless steel roofs, galvanized steel roofs are less expensive.

In short, galvanized steel roofing is one of the popular choices, if you are looking for a metal roof, for your construction.
