WF (Wide Flange) steel
WF steel or Wide Flange Beam is Hot rolled steel (Hot Rolled) Designed specifically for load-bearing applications in architecture and engineering. A key feature is that the flanges are of uniform thickness and parallel along their entire length, unlike... I-Beam steel The wings have a slope.
Our products are manufactured according to international standards, such as: TIS 1227-2015 Or, JIS G3101 offers various grades to choose from. SS400 (General standard) and SM520 (High Tensile – for high tensile strength, such as high-rise buildings or bridges)
Why choose WF steel from AY Contento?
- Superior Strength (Maximum load capacity): Due to its cross-sectional shape with a high moment of inertia, it has excellent resistance to torsional and compressive forces, allowing for a reduction in the number of piles or the size of the foundation.
- Construction Speed: Factory-prepared components (cut and drilled) can be immediately assembled on-site using a bolt and nut system, reducing construction time by over 50% compared to concrete work.
- Design Flexibility: Suitable for architectural projects requiring long column spans or wanting to showcase a loft-style structure.
- Cost Effective: Compared to its reduced lifespan and recyclability, WF steel is a cost-effective long-term option.
Applications
- Columns and Beams: The main structures of high-rise buildings, factories, warehouses, and shopping malls.
- Bridge work: Overpass structures, pedestrian overpasses
- Renovation work: An extension structure that requires a lighter weight than concrete but with equal strength.
- Roof structure: Rafters or purlins for wide-span roofs.

Frequently Asked Questions (FAQ)
In the practical terms of the Thai market. They are usually the same thing. But if we separate them according to the traditional standards:
- WF (Wide Flange): Typically based on American standards (ASTM).
- H-Beam: Based on Japanese Standards (JIS) or Thai Industrial Standards (TIS).
- summarize: If you order in Thailand, you will mostly get specifications based on JIS (H-Beam), but technicians and engineers commonly refer to it as WF.
The standard length is 6 meters However, for larger sizes (150mm and above), factories usually produce them in longer lengths. 9 meters and 12 meters. It was designed to fit the column spacing of the large building.
