Instruction of I Beam
The I-beam is a high strength, large span structural timber beam that is widely used in construction and engineering projects. Generally speaking, I-beams include S-beams, universal beams, H-beams or wide flange beams. However, these beam sections differ in terms of size, strength and application.
I-beams consist of a horizontal member – the flange – and a vertical member – the web. The webs resist shear forces, while the flanges resist most of the bending moments. Due to its effectiveness in carrying bending and shear loads, it is most commonly used in steel buildings, bridges and civil engineering

Applications of I Beam
I-beams are made from steel, aluminium and other low alloy steels. Although I-beams have the same appearance as beribboned beams, I-beams have the appearance of a building foundation material with many different uses, such as building bridges. I-beams are designed to allow the beam to bend, rather than buckle, under high load pressures. Standard bea are used in steel construction. they are versatile and can withstand stresses. The shape of the I-beam does not require additional steel and is therefore cost effective. I-beams are considered to be the universal beam of the construction world
- Support beams for construction,facilities and engineering.
- Support channels, angles.
- Workplace platforms.
- Factories, shops, warehouses.
- Truck bed framing.
Key Features of I Beam
- The beams are lighter, making them a better choice for buildings where forces and weight on walls can cause structural problems.
- They have a thinner central web, which means they cannot withstand the same forces as flange beams.
- You can only build I-beams to the size allowed by the manufacturer’s milling equipment.
- I-beams are available for spans of 33 to 100 feet. Like wide flange beams, I-beams have top and bottom flanges, but they are not the same width or length.
- Unlike wide flange beams, I-beams are a single piece of metal and riveting and welding are not involved in their manufacture.
Packing and Shipping of I Beam
The packaging of our products (eg. weathered corrugated steel, weathering corrugated steel,corten steel columnl,hot rolled stainless steel plate) ensures that they will not be damaged during transport. For export purposes, the usual export packaging is done in wooden crates or crates. All hr sheet metal, plates and coils are marked with a logo (company mark), grade, size and batch number. On request, we can customise the marking on the product,such as spcc cold rolled steel.



FAQ
- Find the beam to be ordered on the steel drawing plan and go to the general description in front of the building plan.
- Make a note on the paper of the type of flange of the beam.
- Make a note of the flange measurements.
- Write down the weight per foot of the beam.
- Write down the total length of the beam.
- Go to the detail page of the steel beam installation drawing and the building plan showing the type of beam connection.

The I-beam is designed so that it can bend, rather than buckle, under high stresses. When the beam is loaded, the forces are transmitted vertically, thus supporting the other members of the beam. I-beams are made mostly of steel, thus ensuring structural integrity and providing continuous strength and support.
If the basic allowable bending stress for a steel beam is approximately 23,000 lbs/square inch, the actual bending stress that the beam can be subjected to under these conditions is approximately 6,100 lbs/square inch when considering the span and lack of restraint.
