They are available in square cross-sections with sides varying from 5 to 250 mm. They are widely used in all constructions of steel grillwork for windows, gates etc. Commonly used cross-sections have sides varying from 5 to 25 mm with weights of 0.20 kg and 4.90 kg per meter length, respectively.

This section is shaped like the letter ‘T’ and consists of a flange and a web. The overall dimensions and thickness designate it. These parts are available in different sizes from 20 mm × 20 mm × 3 mm to 150 mm × 150 mm × 10 mm. The corresponding weight per meter length is…

This form of steel is available in various shapes and sizes. It is manufactured from sheets of mild steel, which are machine cut and extruded or stretched. Expanded metal is widely used to reinforce concrete in foundations, roads, pavements, bridges, etc. It is also used for lathing material and partitions.

These are made by passing steel sheets through grooves. By bending and pressing these grooves, steel sheets and corrugations are formed on the sheets. These corrugated sheets are usually galvanized and are called galvanized iron sheets or GI sheets. These sheets are widely used for roof covering.

Channel sections consist of a web with two equal flanges. A channel section is designated by web height and flange width. These parts are available in different sizes from 100 mm × 45 mm to 400 mm × 100 mm. The corresponding weight per meter length is 5.80 kg and 49.40 kg respectively.hows a channel…

Angle segments can be equal legs or unequal legs. Equilateral sections are available in sizes ranging from 20 mm × 20 mm × 3 mm to 200 mm × 200 mm × 25 mm. The corresponding weight per meter length is 0.95 kg and 73.60 kg respectively. Unequal angle sections are available in sizes.varying from…

Following are the different forms in which steel is available in the market.

Although plain concrete is very strong in compression, it is very weak in tensile strength. Therefore, steel is being used as reinforcement in concrete as it is equally strong in compression and tension. The steel for reinforcing is generally in the form of round bars varying in diameter from 5 to 40 mm, sometimes bars…

Steel can be used for various purposes in construction works. As a structural material in trusses, beams, etcAs a non-structural material for grills, doors, windows, etc.In steel pipes, tanks etcIn Sanitary and Sewerage Fittings, Rainwater Fittings etc.Corrugated sheets.As reinforcement for concrete.

Steel is a mixture of iron and carbon. It is highly flexible, flexible, malleable and weldable. Steel has higher tensile and compressive strength and is also more brittle.
