Steel angle is popularly applied by modern buildings, equipment, factory shops & warehouses and everyday life for its low cost and reliable performances. They tend to be used as supporting or structural components for construction.

What is cold-formed steel?

Cold-formed steel (CFS) members are made from structural quality sheet steel that are formed into C-sections and other shapes by roll forming the steel through a series of dies. No heat is required to form the shapes (unlike hot-rolled steel), hence the name cold-formed steel. A variety of steel thicknesses are available to meet a wide range of structural and non-structural applications.

Value-benefit of steel

It as a construction material has many advantages. For example, It doesn’t shrink or split, won’t absorb moisture, and resists warping, termites, and fire.

As a uniformly manufactured product, the quality of It is very consistent. That consistency translates into less scrap to haul off because there is less waste — all of it recyclable. In addition to lowering scrap disposal expense, the fire resistance of It framing also can help reduce project costs through discounts on builders’ risk and other course of construction insurance requirements.

It physical properties allow it to be used in a wide range of environments. It’s strength and ductility, for example, make it ideal for construction in regions subject to high winds or earthquakes. Moreover, a study, showed that the zinc coating on steel framing materials can protect against corrosion for hundreds of years.

And because each piece of It contains a minimum of 25 percent recycled content, is 100 percent recyclable at the end of its lifespan, and emits no volatile organic compounds — it’s an exceptionally sustainable building material.

It also provides numerous advantages in terms of the construction process itself. It is light making it easy to ship, handle and assemble.

Moreover, greater strength means less material. For example, if a project calls for stick framing, the strength of allows it to be installed on 24” centers rather than traditional 16” centers — meaning fewer studs to install.

And because It is manufactured to exacting standards, it is ideally suited for manufacturing into panels and trusses which — because It is light in weight — can be quickly and easily installed with fewer framers on the job.

Given those advantages, some builders have found that ordering factory-manufactured steel panels and trusses is an ideal way to move into steel framing because it minimizes the need for skilled framers, and provides access to experienced design and layout pros.

In addition to speeding up the framing process, It panels contain pre-punched holes designed to accommodate rapid mechanical, electric and plumbing installation after the framing is complete.

Training

It is not difficult to train a crew to work with It. Experienced framers find it relatively easy to learn to frame with steel. Aside from applying their existing skills to a new set of framing components — for example, steel C section studs instead of wood studs; formed steel single tracks instead of top and bottom wood plates; and hex-, pan- and bugle-head screws for framing in addition to pins (nails for steel connections) — framers only need to spend a bit of time mastering the use of a small number of new tools and fasteners.

The list of basic It framing tools is rather short. A typical toolset might include an adjustable-torque screw gun, bits and bit holders for structural steel-to-steel connections, a hand seamer for positioning and bending steel, a chop saw, a pneumatic pin-nailer for steel-to-steel connections and sheathing-to-steel connections, clamps, aviation snips, a swivel-head electric shear, and a magnetic level.

What is steel angle?

Steel angle, also named angle iron, or steel angle bar, is basically manufactured by hot-rolled carbon steel or high strength low alloy steel. It has L-cross shaped section with two legs - equal or unequal and the angle would be 90 degree. Structural steel angles have lots of dimensions to comply with your uses. In addition, bespoke sizes are available.

What steel angle can my company provide?

As popular structural material, angle steel is largely used in bridge building, construction and engineering. According to the steel content, angle steel can be divided into mild steel angle and HSLA steel angle.

Mild carbon steel angle contains A36, S235JR, q235, SS400, SS490, ST37.

HSLA carbon steel angle contains A572 & A588.

According to the surface treatment, angle steel has three types - black (no treatment), hot-dip galvanized and painted.

Many uses of steel angle bars:

Supporting & structural factors - bridges, warehouses, shelves, cable towers, power towers, communication towers, equipment, etc.

Everyday life uses - bed frames, chairs, benches, fencing posts, frames for supporting air conditioner, coffee tables and so on.

Leg (Flange) Thickness: The thickness of the leg (“C”).

Other terms: Fillet radius: The curved portion, where the inside transition between the web and flange occurs is called a fillet. The radius of the fillet is called the fillet radius (not always provided)

Structural Angle is a steel bar that has an L-shaped cross section. It is a piece of structural iron or steel in the form of a 90 degree angle. It is ideal for all structural applications, general fabrication and repairs. This item can have equal sized legs (or flanges); this is typically known as equal leg angle. Legs (or flanges) that are differently sized are typically known as unequal leg angle.

The size measurement of structural angle is commonly specified using the length of each leg (flange) and the thickness of the leg (flange). Dimensions in North America are typically in inches and in the UK, millimeters.

Because Cold-formed steel framing is light weight, extremely strong, noncombustible, and relatively easy to install, it has dominated the market for interior, non-loadbearing partition walls in commercial construction.  Now, with advanced technological developments like panelized systems, the building community is using for structural applications in mid-rise and multi-housing buildings.

In fact, cold-formed steel framing is rapidly becoming the material of choice for student dormitories, assisted living facilities, and hotels across the country where prudent developers are interested in maximizing their return on investment.
