Buyer's Digest

Use this page as a product-first sourcing checkpoint before sending an RFQ. Category: Building Materials. Confirm application fit, capacity, materials, destination, lead time and compliance requirements before comparing suppliers.

Original product description

This customizable steel structure material is offered for industrial construction and prefabricated building projects. The listed product identity specifies Q355B steel, an anti-rust supply configuration, steel beams as the construction members, and bolted connections.

Available cross-section forms include I-beams, H-beams, channels, and angles. The supplied technical information lists a carbon-steel density of 7,850 kg/m³ and Grade 8.8 bolts with a stated minimum tensile strength of 800 MPa.

Weld strength is not fixed in the source information because it depends on the welding method, electrode type, and other fabrication details. Sample-based customization is available, allowing the structure and components to be discussed against project drawings or reference requirements.

Important specification note: the product title identifies Q355B, while another supplied specification field lists Q345B / Q460C. Buyers should therefore confirm the exact steel grade for the quotation and require it to match the approved drawings, material documentation, and order specification.

Before procurement, confirm the required member profiles, section dimensions, connection layout, bolt quantities and grade, welding procedure, surface treatment, dimensional tolerances, design loads, applicable structural standard, inspection plan, and documentation package.

Also verify whether the stated package dimensions and gross weight apply to the proposed configuration. Shipping method, loading arrangement, delivery schedule, installation scope, and project-specific corrosion-protection requirements should be agreed separa
