The Hot‑Rolled Steel Section produced by Guojian's factory is highly suitable for heavy-load engineering projects such as large-scale steel structure industrial plants, high-rise buildings, bridges and municipal infrastructure, photovoltaic power systems, heavy industrial equipment bases, and large-span infrastructure.
Large-scale steel factory buildings, heavy-duty workshops, prefabricated steel structures, warehouse and logistics parks, and large portal rigid frame projects; suitable for constructing main frameworks requiring long spans and high load-bearing capacity.
Urban elevated structures, bridge supports, utility tunnel steel structures, municipal auxiliary facilities, steel pedestrian bridges, and seismic reinforcement/retrofitting projects; features stable material properties and a high safety factor, meeting infrastructure acceptance standards.
Steel structures for centralized step-up substations in large photovoltaic (PV) plants, auxiliary steel structures for PV facilities, wind power equipment bases, and main frameworks for new energy industrial parks; offers strong weather resistance and maintains structural integrity under long-term loads.
High-rise residential frameworks, steel-structure office buildings, and prefabricated load-bearing skeletons; ensures uniform structural stress distribution and superior seismic performance.
Compatible with infrastructure projects in Southeast Asia, the Middle East, Africa, and Europe; supports customization to various international standards; suitable for bulk procurement for overseas factory construction and industrial park projects.
For heavy-load, long-span main frameworks, prioritize H-beams for superior flexural load-bearing capacity and structural stability.
For secondary beams, purlins, and bracing/reinforcement structures, I-beams, channel steel, or angle steel may be used to optimize material costs.
For outdoor, humid, or coastal projects, apply anti-corrosion coatings and rust removal treatments in advance to prevent future corrosion.
Store on a flat, dry surface and elevate the materials to prevent rust and oxidation caused by contact with standing water.
Stack materials separately based on specifications, material types, and batches to avoid mixing or incorrect usage.
Cover long-term inventory with waterproof tarps to prevent oxidation and surface rust caused by sun and rain exposure.
On-site cutting, drilling, and welding must adhere to steel structure construction specifications to avoid compromising the mechanical properties of the material due to high temperatures. Cut edges must undergo rust removal, grinding, and anti-corrosion repair to prevent exposed metal from rusting.
Verify the straightness and verticality of profiles before installation; deformed profiles must not be installed directly.
Ensure tight contact at bolted connections; use shims to level out any excessive gaps.
Perform a comprehensive alignment and reinforcement check after the main steel structure is installed to ensure overall stability.
A: Yes. We manufacture full specifications compliant with GB, EN, and ASTM standards and provide corresponding material certificates and mechanical test reports to meet overseas project acceptance requirements.
A: We offer rust removal, painting, anti-rust coating, hot-dip galvanizing, and shot blasting, making them suitable for highly corrosive outdoor environments and coastal areas with salt spray.
A: We provide free product quotes, detailed price lists, material certificates, mechanical test reports, and factory conformity certificates, supporting project coordination, supervision acceptance, and export customs clearance.
Based on client construction drawings, load parameters, application scenarios, and relevant standards, we optimize profile specifications to reduce steel consumption and control project costs, eliminating waste and selection errors.
Tailored to specific operating conditions—such as industrial plants, bridges, new energy projects, and overseas infrastructure—we provide solutions for heavy-load reinforcement, outdoor anti-corrosion, low-temperature weather resistance, and compliance with overseas standards, matching specific project needs one-on-one.
We provide packing lists, customs declaration documents, and qualification certificates in both Chinese and English. Services include supervised loading, moisture-proof packaging, and reinforcement to withstand long-distance ocean transport, preventing deformation and rust to ensure the intact delivery of overseas orders.
We offer end-to-end guidance on selection, installation advice, and technical Q&A. For bulk orders, we provide long-term supply guarantees and stable pricing structures, making us an ideal partner for long-term strategic cooperation with engineering contractors.
