TMT/Beam/Channel/Angle

TMT steel bars are the steel bars that are manufactured with a unique metallurgical process known as Thermo Mechanical Treatment. These TMT bars are approved by the Bureau of Indian Standards for  construction projects.

TMT

A G Universal Limited is a supplier and manufacturer and supplier of high quality TMT bars in India. We manufacture TMT steel bars in different sizes, grades and specification as per national and international standards. We also export our products in many countries.

TMT (Thermo-Mechanically Treated) bars are high-strength reinforcement bars. They have a tough outer cover and a soft inner core. A G Universal Limited produces superior quality TMT bars with higher strength coupled with flexibility.

TMT bars are widely used in concrete reinforcement structures, bridges, flyovers, dams, industrial structures, buildings, underground platforms in metro railways, thermal plants and hydral power plants. There are different types of TMT based on their grades, which refer to the number of stress levels used to deform it. They are Fe-500 grade, Fe-550 grade and Fe-415 grade. Fe indicates the chemical symbol for iron. The Fe-500 grade TMT bar has more bending ability and an excellent resistance of dynamic loading. Fe- 550 is similar to Fe-500 but it differs in the yield and tensile strength. Fe-415 grade is not used now-a-days. Fe-500 TMT bars are used mainly in buildings, bridges and other concrete structures while Fe- 550 TMT bars are used for coastal, marine and underground structures.

TMT steel bars are available in following sizes:

• 8mm, 10mm – They are used in slabs and stairs up.
• 12mm,16mm,20mm,25mm – They are used in beam and columns
• 32mm, 36mm – They used in dams and bridges

Various features of TMT bars available from A G Universal Limited are:

• They are very pure to provide enhanced strength and durability to the structure.
• They bond perfectly with cement and hence are more resilience to any kind of load.
• They are earthquake-proof due to higher strength and ductility.
• They are anti-corrosive.
• They are easily bendable due to their soft, ferrite and pearlite core.
• They can be easily welded, lap-welded and arc-welded.
• They have a high fatigue resistance.

Beam

A beam is a structural element that mainly resists the load applied laterally to the beam’s axis. It’s mode of deflection is primarily done by bending. The load applied to the beam results in reaction forces at the beam’s support points.

A G Universal Limited is a supplier and manufacturer of high quality beams in India. We manufacture beams in different sizes, grades and specification as per international guidelines. We also export our products in many countries. A beam is a structural steel product which is used to support heavy loads. It is also known as universal beam or Rod Steel Joist (RSJ). A beam differs from a bar. A beam has a property to support pressure and strain while a bar intended to take a pressure.

A beam can be divided into many types based on support, geometry and cross-section. Based on support a beam is of 7 types:

1. Continuous Beam: This type of beam can be extended for two or more supports.
2. Over-hanging Beam: It can be extended beyond its support on one side.
3. Double Over-hanging Beam: It is extended beyond its support on one side.
4. Simply Supported Beam: It is supports at the ends and is free to rotate.
5. Fixed Beam: It can be supported at the end but cannot rotate.
6. Trussed Beam: It is reinforced by a rod or a cable to make a truss.
7. Cantilever Beam: It is fixed on one end but it projects outwards.

Based on geometry, beams are of 3 types:

1. Straight Beam: This type of beam is straight in shape.
2. Tapered Beam: It has a tapered cross-section.
3. Curved Beam: It is curved in shape.

Based on cross-section, there are 4 types of beams:

1. I-Beam: It has an I-cross section.
2. C-Beam: It has c-cross section.
3. T-Beam: It has a T-cross section.
4. H-Beamor W-Beam: It has flanges that are not tempered and are wider than an I-Beam.

Beams are used in supporting house frames, roof structures, and other secured structures. They have many advantages. They cannot break as the steel endures huge amounts of tensile strength. They are also resistant to fire and corrosion.

A G Universal Limited provides you a wide range of beams such as mild steel beams (I and H shaped), narrow flange beams, parallel beams, parallel flange beams, metal beams (I and H shaped), structural beams (I and H shaped), universal beams, I-Beams, ISMBs (Indian Section Mild Beams), NPB beams, HT beams, W-Beams, and Steel channels.

Channel sections are commonly used where bending occurs about the minor axis with flanges under a stress gradient. For instance, the edges that are in compression with flanges may experience distortional buckling.

Channel

Channels are also known as C channels, channel beams or Parallel Flange Channels (PFCs). They are used in different applications such as buildings, tractor trailers and frame chassis for vehicles. They are manufactured from mild steel, which is hot-rolled. The steel provides strength and rigidity to channels. Dimensional standards should be followed during manufacturing of channels, which should be fabricated and be either painted or galvanized to make them resistant to corrosion.

Channels have both indoor and outdoor usage. At indoor, they are mainly used in holders, covers, frames, inserts, décors, brackets, tracks, slides, etc. whereas at outdoor they are mainly used in railings, rails, rims, sub-girts, etc. They are also used as supportive material while repairing. They are high in demand by civil engineers during construction due to their corrosion-resistant and high support properties. They have perpendicular extensions at the top and bottom. They are lighter and more flexible as compared to beams.

Steel channels are used at walls, pole beam walls, roofs, window and door frames, wood beam supports, vehicle frames, trailers, and metal buildings as described below:

• They are used to build walls for garages, workshops, warehouses, and other metal buildings.
• They can also be used in pole beams to form the walls, where they run horizontally from pole to pole to provide an attachment point for the siding on the exterior.
• They can be used as rafters on light duty roofs.
• They can be used to create secure frames for windows and doors in metal and wooden framed buildings.
• They increase the rigidity and strength of wooden beams.
• They are often used to construct flat-bed trailers, box trailers, travel trailers and RVs.

A G Universal Limited offers a wide range of channels including C-channels, Channel Beams and mild C-steel channels. Our infra-metal shock channels from C3 x 4.1 to C15x50 range of sizes in various lengths of up to 60 feet can help our customers minimize scrap. Various categories of C-channels available with use are roofing sheets, Galvanized sheets, profile sheets, roofing system and pre-engineered building structures.

A G Universal Limited is a supplier and manufacturer of high quality channels and channel beams in India. We manufacture channels and channel beams in different sizes, grades and specification as per international guidelines. We also export our products in many countries.   

Angles are the most basic type of roll-formed steels. They are formed by bending a single angle in a piece of steel. Angle Steel is ‘L’ shaped i.e. 90-degree angled.

Angle

A G Universal Limited produces a wide range of different types of angles for construction applications. Angle is an “L” shaped roll-formed steel with low carbon, manufactured by section rolling mills or bending machines. It is formed by bending a single angle at 90 degree in a piece of steel.  The legs of the “L” can be equal or unequal in length. The angle can bear more weight and stress if it is larger. Both structural steel (such as carbon, alloyed and stainless) and non-ferrous metals (such as aluminum and copper) can be used as source material to manufacture steel angles.

Steel angle is used in construction, machine-building and many other areas for making bridges, warehouses, shelves, cable towers, power towers, communication towers and equipment. It is mainly used as supporting or structural components for construction. It is commonly used to make bed frames, chairs, tables, benches, fencing posts, frames for supporting air conditioner, etc. A few other uses of angles are for brooms, rails, braces, cross-members, liners, truck trailers, truck beds, bicycle racks, motor mounts, brackets, reinforcements, etc. Framing is one of the most common uses for steel angles. Angles are used for door and window framing, arches and other architectural elements.

Steel Angles can be either hot rolled or cold rolled/bent angles. Hot rolled angles are mostly used in industries and manufacturing units as they have a rough surface that makes them suitable for different applications. Hot-rolled steel angles are manufactured from steel billets or blooms, while bent angles are made of steel coils cut into strips of the required width. According to the surface treatment, angles are of three types – black with no treatment, hot-dip galvanized and painted.  Steel angles can be either of equal or unequal angle sizes. Equal sized angles have legs of equal length.
