After in-depth technical communication, review of the project's structural design drawings, and analysis of seismic and load-bearing requirements, we provided a comprehensive solution featuring H-beams, angle steels, and steel plates—all tailored to meet the rigorous standards of government construction. The key product advantages and customizations are as follows:
- H-Beams (Main Load-Bearing Structure): Adopted Q355B (equivalent to ASTM A36) grade H-beams, the core load-bearing component of the building frame. This grade boasts excellent yield strength (minimum 355 MPa) and tensile strength (minimum 470 MPa), enabling it to withstand the building's self-weight, occupancy load, and seismic forces. Customized specifications (height: 200mm-600mm, flange width: 100mm-250mm, web thickness: 6mm-14mm) were provided to match different layers and structural sections of the government building.
- Angle Steels (Structural Bracing & Framing): Supplied Q235B (equivalent to ASTM A283 Gr.C) angle steels for structural bracing, roof truss connections, and wall framing. With excellent ductility and bending performance, the angle steels enhance the overall stability and anti-seismic capacity of the building. Customized sizes (leg length: 50mm-125mm, thickness: 5mm-10mm) were designed to fit the complex connection requirements of the building's non-load-bearing structures.
- Steel Plates (Floor Slabs & Structural Reinforcement): Provided ASTM A36 steel plates for floor slab fabrication and key structural reinforcement areas. The plates feature uniform thickness (8mm-20mm) and high flatness, ensuring seamless welding with H-beams and reliable load transfer. Strict surface quality control (no cracks, inclusions, or defects) was implemented to meet the high standards of government construction.
- Quality Compliance: All steel profiles underwent rigorous quality testing, including chemical composition analysis, mechanical property testing, and dimensional accuracy inspection. They are fully compliant with ASTM international standards and El Salvador's local building codes, with complete quality certificates provided to facilitate project acceptance by government authorities.
