• Global logistics support: FOB Tianjin or Qingdao port; DDP available for key EU/NA markets
• Documentation included: CE, SGS, ASTM, and AS/NZS compliance certificates shipped with every order

China-Based Manufacturing — ISO-Certified, Audit-Verified, Export-Optimized

We’re not a trading company posing as a factory. As a China-headquartered manufacturer since 2001, we operate nine integrated subsidiaries across R&D, precision steel fabrication, panel production, and on-site installation — all under one ISO 9001/14001/45001 management system.

• Factory transparency: Alibaba Verified Pro Supplier; CNAS-accredited quality lab on-site
• No middlemen: Direct pricing from source — up to 30% lower than traditional suppliers, verified by third-party cost benchmarking
• Export-ready infrastructure: 48,000 m² smart manufacturing campus; 23+ years serving 50+ countries
• Local support network: Technical engineers available for site supervision in North America, UAE, and Southeast Asia

Carport Structures Engineered for Long-Term Asset Protection — 50-Year Warranty Included

A carport isn’t just shelter — it’s an asset protection investment. Our hot-dip galvanized steel frames and insulated sandwich panels deliver structural integrity, thermal efficiency, and corrosion resistance across climates — from Dubai’s 50°C desert heat to Montreal’s -30°C winters.

• Load-rated design: Wind resistance up to 150 km/h; snow load capacity up to 2.5 kN/m²; seismic grade up to 8
• Durability guaranteed: 50-year structural warranty — backed by AISC and CSA-certified engineering
• Low-maintenance operation: Pre-finished color-coated steel; zero painting or sealing required for first 15 years
• ROI-focused specs: 30–50 year lifespan; 92% material recyclability at end-of-life

Combo Building Solutions — Modular, Interchangeable & Site-Adaptable

Nuestra combo approach eliminates costly project fragmentation: one supplier delivers full building systems — structural frame, cladding, doors, insulation, and accessories — engineered as a single, interoperable unit.

• Plug-and-play integration: Standardized bolted connections between carport, warehouse, workshop, and poultry house modules
• Site flexibility: Stable on flat ground, slopes, or low-lying terrain — no concrete foundation required for most configurations
• Expandable architecture: Add mezzanine floors, loading docks, or gutters without redesign or re-engineering
• Fast-track delivery: BIM-integrated design ensures 100% component compatibility — zero field rework

Metal Building Systems — Precision-Fabricated, Code-Compliant & Fully Documented

This is not generic “metal building.” It’s a metal building system engineered to EN 1090, ASTM A653, and AS/NZS 4600 standards — with traceable mill certificates, weld procedure qualifications, and full-load calculation reports provided before shipment.

• Trazabilidad de materiales: All H-beams, purlins, and trusses carry QR-coded batch IDs linked to raw material test reports
• Design-to-delivery alignment: AutoCAD + Tekla Structural Designer models match physical components down to ±1.5 mm tolerance
• Code-ready documentation: Full set of stamped structural drawings, fire-rating data, and wind/snow load calculations — delivered digitally and in print
• Installation certainty: Free detailed assembly drawings + HD installation video library; optional engineer dispatch available

Preguntas frecuentes

Is Hebei Weizhengheng a factory or a trading company?

We are a vertically integrated manufacturer — not a trading intermediary. Since 2001, we’ve operated nine subsidiaries across R&D, steel fabrication, panel production, and on-site installation — all under one ISO 9001/14001/45001-certified management system. Our 48,000 m² smart manufacturing campus in Shijiazhuang produces steel structure carport, combo building, y metal building systems end-to-end.

Do you offer factory audits or third-party verification?

Yes. We are an Alibaba Verified Pro Supplier, with CNAS-accredited in-house quality lab and annual SGS/BV audits. Buyers may schedule pre-shipment inspections or request video walkthroughs of our China-based production lines — including galvanizing baths, CNC punching stations, and automated sandwich panel laminators.

What is your standard price validity period for wholesale quotations?

Quotations for wholesaler orders remain valid for 30 days from issue date. Pricing reflects current raw material indices (steel billet, color-coated coil) and confirmed port charges at Tianjin or Qingdao. We adjust only for verified tariff changes or currency fluctuations exceeding ±3% against USD.

Which payment terms do you accept for first-time buyers?

We accept T/T (30% deposit, 70% before shipment), L/C at sight, y PayPal (up to $50,000/order). For qualified wholesaler partners with ≥3 successful shipments, we offer D/P and net-60 terms upon credit review.

How do you ensure dimensional accuracy and component interoperability for combo building projects?

We enforce ±1.5 mm tolerance across all fabricated parts using Tekla Structural Designer–driven CNC machines. Every carport, metal building, and warehouse module shares standardized bolt patterns, purlin spacing, and base plate anchoring — validated via BIM clash detection before cutting begins.

Do you support private-label branding for wholesaler clients?

Yes. We apply customer-supplied logos, labels, and packaging artwork to all steel structure carport y combo building orders ≥100 m². All branding complies with EN ISO 12944 corrosion class C4 requirements and includes UV-stable ink certification.

What structural documentation accompanies each order?

Every shipment includes: stamped structural drawings (PDF + DWG), wind/snow load calculation reports, mill test certificates with QR-coded batch IDs, weld procedure specifications (WPS), and CE/AS/NZS compliance declarations. No additional fee — delivered digitally and in printed hard copy.

What post-installation support do you provide for international buyers?

We supply free HD installation videos, annotated assembly drawings, and 24/7 technical email support.
