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

China Steel: Precision-Engineered Structural Integrity, Backed by 23 Years of Global Delivery

When your project demands zero compromise on strength, longevity, and compliance—especially across seismic zones, high-wind regions, or heavy-snow climates—you need steel that performs as promised. We source certified Q235B, Q345B, and ASTM A572 Grade 50 steel from ISO-certified mills, with full traceability and third-party mill test reports (MTRs) provided for every batch.

• Yield strength guaranteed: ≥235 MPa (Q235B) to ≥345 MPa (Q345B), verified per EN 10025-2 and ASTM A6/A6M
• No hidden substitutions: All structural members—including H-beams, columns, and roof trusses—are hot-rolled or galvanized per project-spec, not substituted with inferior cold-formed alternatives
• Global compliance ready: CE-marked components meet EN 1090-2 Execution Class EXC2/EXC3; AISC-certified welding performed under EN ISO 3834-2
• Real-world validation: 50+ years design life confirmed via accelerated corrosion testing (salt spray ≥1,000 hrs) and fatigue cycle simulation (≥2 million cycles)

Intelligent: BIM-Integrated Design & Smart Manufacturing for Predictable Project Outcomes

“Intelligent” isn’t a buzzword—it’s how we eliminate cost overruns, rework delays, and field coordination errors before fabrication even begins. Our engineering team delivers clash-free, install-ready models—not just static drawings—using Autodesk AutoCAD, Tekla Structures, and SAP2000, fully aligned with your local building codes.

• BIM-first workflow: All custom projects start with coordinated 3D modeling; you receive IFC files + PDF shop drawings + installation video library (free)
• Pre-fab precision: CNC plasma cutting and robotic welding ensure ±1.5 mm dimensional tolerance—reducing on-site adjustments by up to 70%
• Real-time collaboration: Shared cloud portal for markups, RFIs, and revision tracking—no email ping-pong or version confusion
• Logistics-aware planning: Modules designed for optimal container loading (max. 32 m² per 40’ HQ container), minimizing freight cost and port handling time

ISO 9001: Systematic Quality Control—Not Just a Certificate, But Your Risk Mitigation Protocol

ISO 9001:2015 isn’t framed in our office—it’s embedded in every process step, from raw material inspection to final load-test verification. For procurement managers auditing supplier capability, this means documented traceability, auditable non-conformance logs, and zero tolerance for deviation without formal ECN approval.

• Six-stage QC gate: Incoming material check → pre-weld prep → weld procedure qualification → post-weld NDT (UT/MT) → dimensional audit → final load test (1.5x design load)
• Third-party validation: SGS and BV conduct quarterly unannounced audits; all certificates are publicly verifiable via CNAS database
• Supplier accountability: Each steel coil lot carries QR-coded traceability—scan to view MTR, heat number, galvanizing thickness (≥85 µm), and coating adhesion test result
• No “certification theater”: We maintain ISO 9001, ISO 14001, and ISO 45001 under a single integrated management system—audited annually by TÜV Rheinland

Frequently Asked Questions

Is Weizhengheng Group a factory — not a trading company — with full in-house production capability?

Yes. Weizhengheng Group operates nine vertically integrated subsidiaries across R&D, steel processing, panel lamination, BIM design, and logistics — all under one management system. As a Manufacturer, we control every stage: from raw steel sourcing (Q235B/Q345B/ASTM A572) to CNC-cut components, robotic welding, and final load testing. No subcontracting for core structural fabrication.

Do you offer fixed pricing per square meter — and does it include all structural and cladding components?

Yes. Our China Steel warehouse and workshop solutions are priced at a transparent $18–$60/m² — fully inclusive of hot-rolled H-beams, galvanized roof trusses, rock wool or PU sandwich panels, anchor bolts, and standard doors. No hidden line items. Pricing is locked upon order confirmation and covers engineering, fabrication, and pre-assembled kit packaging.

Which payment methods do you accept — and are Letters of Credit supported with full documentation?

We accept T/T, irrevocable L/C at sight, D/P, D/A, PayPal, and Western Union. For L/C transactions, we provide full shipping documents (BL, CO, CI, PL, SGS/BV reports) compliant with UCP 600. All payments are processed through our corporate bank account — no third-party collection agents.

What are your standard port options — and can you handle DDP delivery to EU/US warehouses?

We ship FOB Tianjin or Qingdao by default. CFR and CIF terms are available with verified freight forwarders. DDP is offered to major EU/US logistics hubs (e.g., Rotterdam, Hamburg, Los Angeles, Chicago) — including customs clearance, import VAT handling, and last-mile delivery coordination. Lead time includes port loading and container stuffing verification.

How long does it take from order confirmation to shipment — and is lead time contractually guaranteed?

For in-stock standard designs: ≤21 days FOB Tianjin. For custom-engineered projects: 31–45 days — confirmed in the proforma invoice and enforceable under contract. Delays caused by client-requested design changes or late approvals are excluded. Production scheduling is tracked weekly via shared cloud portal.

Are your buildings engineered for local wind, snow, and seismic loads — and do you provide stamped drawings?

Yes. Every Intelligent project starts with BIM-integrated structural analysis using SAP2000 or Tekla Structures — calibrated to your site’s exact wind speed (up to 70 m/s), snow load (up to 3.5 kN/m²), and seismic intensity (GB 50011 or ASCE 7-16). Stamped engineering drawings and calculation reports are delivered before production begins.

Can you support OEM branding — and do you provide CAD files, BOMs, and packaging marked to our spec?

Yes. As a certified OEM partner, we hand over native AutoCAD and Tekla files, full BOMs with part numbers, and packaging labeled exclusively with your logo, SKU, and handling instructions. No “WZHG” branding appears unless explicitly requested. QR-coded traceability tags on each steel coil link to MTRs and galvanizing test reports.

What quality assurance protocols do you follow — and how is ISO 9001 embedded beyond certification?

Our ISO 9001 system governs six mandatory QC gates: incoming material check → pre-weld prep → WPS qualification → post-weld NDT (UT/MT) → dimensional audit → 1.5x design-load structural test. Third-party auditors (SGS, BV) conduct unannounced quarterly checks. All certificates are CNAS-verified and publicly searchable.

What after-sales support do you provide — and is installation supervision available on-site?

We supply free installation drawings, annotated PDFs, and a video library covering foundation layout, column erection, and panel fixing. For complex projects, we deploy certified engineers as site supervisors — including crane rail alignment, mezzanine floor leveling, and fire-rated partition validation. Warranty claims are processed within 5 business days of documented defect submission.
