China Basic Steel Structure Custom

Specifications & Compliance

Reference specs for our Steel Structure Warehouse Building platforms. Custom configurations available — these are starting points, not limits.

China-Based Steel Structure Manufacturer with Full Customization Capability

We deliver precision-engineered steel structures from our ISO-certified production base in Shijiazhuang — not a trading intermediary, but a vertically integrated manufacturer with 23+ years of export experience across 50+ countries.

• Direct factory control: 48,000 m² facility, 1,000+ engineers and technicians, daily output capacity of 5,000 m²
• No middlemen markup: FOB Tianjin/Qingdao pricing includes full structural design, material sourcing, welding, galvanizing, and panel integration
• Proven compliance: CE, SGS, BV, AISC, AS/NZS, and ASTM-certified; EN 1090-2 execution class EXC2 certified for structural steelwork

Basic Steel Structure Solutions Engineered for Speed, Safety & Scalability

Our “basic” steel structures are not off-the-shelf kits — they’re engineered entry-level systems designed for rapid deployment without compromising structural integrity or long-term performance.

• 30–50 year service life, backed by a 50-year warranty on primary load-bearing components (H-beams, trusses, columns)
• Standardized yet adaptable: Pre-engineered models (warehouse, workshop, garage) start at $15/m², with full parametric redesign available within 72 hours
• Installation-ready documentation: Free BIM-integrated drawings (Tekla, SAP2000), 3D assembly videos, and on-site supervision optional

Steel Structure Buildings Built to Your Exact Technical Specifications

From wind zones (up to 120 km/h) to seismic Grade 8 and snow loads up to 1.5 kN/m² — we engineer every steel structure to your site’s real-world conditions, not generic assumptions.

• Site-specific engineering: Structural calculations, foundation layout, and connection details validated per local code requirements (IBC, Eurocode, GB, AS/NZS)
• Material transparency: Q345B/Q235B hot-rolled H-beams; galvanized coating ≥275 g/m²; sandwich panels with fire-rated cores (rock wool A1, PU B1)
• No hidden revisions: One round of free design iteration included; final stamped drawings issued before production begins

Custom Steel Structures — From Logo to Load-Bearing Layout

True customization means owning the full value chain: design, fabrication, finishing, and logistics — all under one roof, with no minimums beyond functional scale (100 m²).

• End-to-end personalization: Logo embossing on beams, branded packaging, custom panel colors (RAL/FS standard), non-standard spans (up to 60 m clear span)
• Functional adaptability: Crane-supported bays, mezzanine floors, dock levellers, insulated cold-store envelopes (-30°C to +50°C), and livestock ventilation integration
• Fast-track customization: Light customization (color, logo, door/window layout) delivered in ≤31 days; full architectural redesign in ≤45 days

Frequently Asked Questions

Is Hebei Weizhengheng Group a factory — not a trading company?

Yes. We are a vertically integrated China-based steel structure manufacturer, operating nine production facilities across Hebei Province. Our 48,000 m² smart manufacturing base in Shijiazhuang houses full-cycle capabilities: structural design, cutting, welding, galvanizing, panel lamination, and quality control — all under direct engineering supervision. No third-party subcontracting for core processes.

What is the minimum order quantity for basic steel structure custom projects?

The functional minimum is 100 square meters — applicable to all basic steel structure custom configurations (warehouse, workshop, garage, poultry house, etc.). This threshold ensures structural integrity validation, efficient material nesting, and compliance with ISO 9001-certified production scheduling. Smaller test builds require pre-approval and are subject to surcharge.

Do you accept Letter of Credit (L/C) payments — and what are the terms?

Yes. We accept irrevocable L/C at sight, confirmed by a top-50 global bank. Required clauses:

• Full shipment documentation: Commercial invoice, packing list, bill of lading, CE/SGS certificates, and stamped structural drawings
• Partial shipments: Permitted only with prior written agreement
• Discrepancy fee: USD 85 per amendment — billed to opener if documents deviate from PO or proforma

Which ports do you ship from — and can you handle DDP to EU or US destinations?

We operate FOB from Tianjin Port and Qingdao Port. CFR and CIF are standard. DDP is available to major EU and US logistics hubs (e.g., Rotterdam, Hamburg, Los Angeles, Chicago), subject to customs classification verification and duty calculation prior to quotation. All DDP quotes include bonded warehouse handling, import VAT, and inland freight to site address.

How long does it take from order confirmation to shipment for a basic steel structure custom order?

Standard lead time is 31–45 days, calculated from signed drawing approval and receipt of deposit. Timeline assumes:

• Site data (wind/snow/seismic specs) provided within 48 hours of order
• No revision to approved structural model beyond one free iteration
• Material availability confirmed at order entry (Q345B H-beams, rock wool sandwich panels)

Can you supply certified structural calculations and stamped drawings for local permitting?

Yes. Upon order confirmation, we deliver EN 1090-2 EXC2-compliant structural calculations, foundation layout plans, and connection details — stamped by our in-house AISC-certified engineers. Documentation aligns with IBC, Eurocode, AS/NZS, or GB standards per your jurisdiction. Re-stamping for local authority submission is included at no extra cost.

Do you support OEM branding — including logo embossing on structural members?

Yes. We apply custom logos via laser engraving or embossing directly onto primary load-bearing components (H-beams, columns, trusses). Minimum batch: 100 m². Branding extends to packaging cartons, panel labels, and digital asset delivery (PDF + DWG + Tekla models with embedded brand metadata).

What warranty coverage applies to basic steel structure custom systems?

We provide a 50-year warranty on primary steel members (H-beams, trusses, columns) against material defect and structural failure under specified design loads. Secondary components (sandwich panels, fasteners, doors) carry 10-year limited warranties. Warranty activation requires adherence to installation guidelines and submission of signed commissioning report.

Do you offer on-site installation supervision — and what does it include?

Yes. Our engineers conduct turnkey supervision for critical milestones: foundation anchor bolt placement, main frame erection, panel alignment, and final connection torque verification. Scope includes:

• Pre-installation briefing with local contractor (in English or local language)
• Real-time QA/QC checklist sign-off per ASTM A6/A6M and EN 1090-2
• As-built drawing update and handover within 5 working days post-completion
