Arch Roof Agricultural Warehouse Building Manufacturer in China

Specifications & Compliance

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

Arch Roof Steel Structure Buildings — Engineered for High-Clearance Agricultural & Industrial Use

Our arch roof steel buildings deliver unmatched interior clearance—no internal columns, no load-bearing walls—maximizing usable floor space for machinery, storage, or livestock movement. Designed and certified to withstand local wind and snow loads (up to 150 km/h wind speed and 2.5 m snow depth), these structures eliminate costly foundation upgrades and reduce installation time by 30% compared to conventional gable-roof alternatives.

• No internal supports: Full-span arch design clears 12–30 m width without columns
• Pre-engineered compliance: CE, AS/NZS, and AISC-certified structural calculations included
• Faster deployment: Typical erection completed in under 7 days for a 2,000 m² unit
• Roof-integrated options: BIPV-ready mounting rails and rainwater gutter systems available

Agricultural Warehouse Building — Purpose-Built for Farm Operations & Cold-Chain Logistics

Our agricultural warehouse building line serves farms, co-ops, and agri-logistics providers with durable, insulated, and rapidly deployable facilities—from poultry houses operating at +32°C ambient to cold-storage sheds maintaining -30°C. Every unit is engineered to ISO 9001-certified standards and includes corrosion-resistant galvanized framing (Z275 coating) and fire-rated rock wool sandwich panels (A2 class).

• Multi-application ready: Configurable for poultry, dairy, grain, hay, or refrigerated storage
• Thermal performance: U-values as low as 0.28 W/m²K (with 100 mm rock wool core)
• Fast ROI: 40% lower lifetime maintenance cost vs. concrete-block alternatives (based on 10-year lifecycle analysis)
• Modular scalability: Expand lengthwise in 6 m increments without redesign or re-permitting

Manufacturer — Integrated EPC Provider with 23 Years of Global Steel Structure Delivery

As a vertically integrated manufacturer, we control every stage—from raw material procurement (certified Q355B and ASTM A36 steel) to precision CNC cutting, robotic welding, and final QA inspection. With 9 subsidiaries, 48,000 m² smart manufacturing campus, and daily output capacity of 5,000 m², we guarantee consistent quality, traceable batch documentation, and on-time delivery—even for 10,000+ m² turnkey projects.

• Full-cycle ownership: In-house R&D, BIM modeling (Tekla + SAP2000), fabrication, and installation supervision
• Export-ready scale: Delivered to 50+ countries; 85% of orders shipped FOB Tianjin/Qingdao within 35 days
• Quality traceability: Each beam carries laser-engraved QR code linking to mill test reports and weld logs
• No subcontractor risk: 100% of structural components fabricated in our ISO 9001/14001/45001-certified facility

China-Based Steel Structure Factory — Strategically Located, Export-Optimized, and Audit-Ready

• Audit-ready infrastructure: On-site labs for tensile testing, salt-spray corrosion trials, and non-destructive weld inspection
• Trade flexibility: Accepts L/C, D/P, T/T, and PayPal; supports DDP terms for key EU/US destinations
• Local support network: Technical reps stationed in Dubai, Lagos, and São Paulo for pre-sales engineering and post-installation follow-up

Frequently Asked Questions

Is Weizhengheng Group a factory-direct manufacturer — not a trading company or agent?

Yes. Hebei Weizhengheng Modular House Technology Co., Ltd. is a vertically integrated manufacturer with nine wholly owned subsidiaries, 48,000 m² smart manufacturing campus, and full-cycle capabilities — from raw steel procurement (Q355B/ASTM A36) to CNC cutting, robotic welding, BIM-based engineering (Tekla + SAP2000), and on-site installation supervision. No subcontractors are used for structural components.

Do you offer certified structural engineering drawings for Arch Roof and Agricultural Warehouse Building projects?

Yes. Every Arch Roof and Agricultural Warehouse Building order includes CE-, AS/NZS-, and AISC-certified structural calculations, stamped by our in-house registered engineers. Drawings comply with local wind (up to 150 km/h), snow (up to 2.5 m), and seismic requirements — validated using SAP2000 and 3D3S software.

What is your minimum order quantity for customized China-based production — and does it apply to all configurations?

The MOQ for fully customized Arch Roof, Agricultural Warehouse Building, and other steel structure solutions is 100 square meters. This applies uniformly across all configurations — including color, size, insulation grade, panel type (rock wool/A2 fire-rated), and graphic customization. No exceptions or tiered MOQs.

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: commercial invoice, packing list, BL, certificate of origin, CE/SGS test reports, and mill test certificates. All L/C terms are negotiable per UCP 600 standards.

What is your standard lead time — and can it be accelerated for urgent Manufacturer-level orders?

Standard lead time is 31–45 days after deposit receipt and final drawing approval. For orders exceeding 5,000 m², we allocate dedicated production lines and can compress lead time to 25 days — subject to confirmed material availability and pre-approved engineering sign-off.

Do you ship FOB from China ports — and which ports are operational for containerized steel structure shipments?

Yes. We ship FOB from Tianjin Port (primary) and Qingdao Port (secondary). Both ports support full-container-load (FCL) shipments of pre-assembled arch roof kits, wall panels, and structural frames. Average inland haul time to Tianjin is 3 days; rail access to Qingdao is available for bulk consignments.

Can you supply third-party inspection reports — and which agencies do you work with for pre-shipment verification?

Yes. We accommodate SGS, BV, and TÜV inspections at our facility prior to shipment. Inspection scope covers dimensional accuracy, weld integrity (UT/PT), galvanizing thickness (Z275), panel fire rating (A2), and corrosion resistance (500-hr salt-spray tested). Reports issued within 48 hours of completion.

Do you support OEM branding — and what level of customization is available for Manufacturer clients requiring private-label delivery?

Yes. We support full OEM execution for Arch Roof and Agricultural Warehouse Building clients: custom logos (laser-etched or embossed), branded packaging, label printing (EN/ISO-compliant), and graphic panel integration. All customization starts at 100 m² — no volume premium applied.

What warranty and after-sales support do you provide — especially for international China-based installations?

We provide a 50-year structural warranty backed by ISO 9001/14001/45001-certified processes. For overseas installations, we supply free detailed assembly drawings + video guides. Optional on-site supervision by certified engineers is available — with teams deployed from Dubai, Lagos, or São Paulo for regional technical follow-up.
