China Manufacturer And Erection Of Steel Trusses

Specifications & Compliance

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

China-Based Steel Truss Manufacturer with Full EPC Capability

We design, fabricate, and erect steel trusses in-house — no third-party subcontracting. As a certified China manufacturer operating since 2001, we control every stage: structural engineering, precision cutting, galvanizing, welding, quality inspection, and on-site erection support.

• Proven capacity: 5,000 m² daily production output across 9 integrated facilities
• Global compliance: CE, AISC, AS/NZS, ASTM, and EN 1090-certified fabrication
• Erection-ready delivery: All trusses supplied with stamped shop drawings, bolt torque specs, and installation video guides — free of charge
• On-demand support: Optional engineer dispatch for supervision (FOB or DDP terms available)

Professional Steel Truss Erection Services — From Foundation to Final Tie-Down

We don’t just supply trusses — we ensure they’re erected correctly, safely, and on schedule. Our erection service includes site assessment, anchor bolt layout verification, crane coordination, sequence planning, and post-installation alignment checks — all managed by certified structural engineers.

• Speed-to-site: Typical erection timeline: 3–7 days for 1,000 m² warehouse (with client-provided foundation & crane)
• Risk mitigation: All erection teams carry liability insurance; work adheres to ISO 45001 safety protocols
• Documentation included: As-built drawings, load test reports, and erection sign-off certificates
• Flexibility built-in: Support for hybrid erection (client-led + our supervision) or full turnkey execution

Precision-Fabricated Steel Trusses — Engineered for Real-World Loads

Every truss is engineered for your exact project conditions — not generic “standard” specs. Our steel trusses are hot-rolled or cold-formed to tolerance ±1.5 mm, pre-galvanized (Z275), and weld-tested per EN ISO 3834-2.

• Load-resilient design: Validated for wind speeds up to 65 m/s and snow loads up to 3.5 kN/m²
• Material traceability: Mill test reports (MTRs) provided for all primary steel members
• Connection integrity: Bolted joints designed to AISC 360; welded nodes inspected via ultrasonic testing (UT)
• Long-term performance: 50-year structural warranty backed by independent SGS validation

Frequently Asked Questions

Is Weizhengheng Group a certified China manufacturer of steel trusses with in-house erection capability?

Yes. We are a vertically integrated China manufacturer — not a trading agent — operating since 2001. All steel trusses are designed, fabricated, galvanized, welded, inspected, and erected by our own engineering teams across nine production facilities. We hold AISC, EN 1090, CE, and ISO 45001 certifications for both fabrication and on-site erection.

Do you provide stamped structural drawings and erection documentation for international building approvals?

Yes. Every order includes stamped shop drawings (PDF + DWG), bolt torque specifications, wind/snow load calculations, and installation video guides — all compliant with AS/NZS, ASTM, and Eurocode requirements. We support third-party review submissions to local authorities.

What is your standard lead time for custom steel trusses, and can it be expedited?

Standard lead time is 31–45 days from confirmed order and approved drawings. For urgent projects, we prioritize production slots and offer accelerated timelines — down to 21 days — subject to material availability and structural complexity.

Which ports do you use for FOB shipments, and can you coordinate container loading and customs clearance?

We primarily ship via Tianjin Port and Qingdao Port. Our logistics team handles full export documentation, container stuffing, and customs clearance under FOB, CFR, or CIF terms. We also support DDP delivery to EU/US destinations with bonded warehousing options.

How do you ensure dimensional accuracy and weld integrity for steel trusses supplied internationally?

We enforce ±1.5 mm tolerance on all hot-rolled and cold-formed members. Each weld undergoes visual inspection and ultrasonic testing (UT) per EN ISO 3834-2. Mill test reports (MTRs) and non-destructive test records accompany every shipment.

Can you supply steel trusses with pre-drilled anchor bolt patterns matching our foundation layout?

Yes. Our BIM-based design process integrates client-provided foundation drawings. We pre-drill all base plates to match your anchor bolt coordinates and deliver with annotated layout diagrams and verification templates for field alignment.

Do you accept letters of credit (L/C), and what are your payment terms for first-time buyers?

We accept irrevocable L/C at sight, T/T (30% deposit, 70% before shipment), and D/P. For verified first-time buyers, we offer flexible terms: 10% deposit with balance against copy of BL — backed by SGS pre-shipment inspection.

What warranty coverage applies to your steel trusses, and how is it enforced?

We provide a 50-year structural warranty on all steel trusses, validated by SGS. Coverage includes material defects, weld failure, and galvanizing degradation — backed by replacement or on-site repair. Warranty claims require submission of as-built documentation and photographic evidence.

Do you support hybrid project execution — where our team handles civil works while you manage erection?

Yes. We routinely execute hybrid delivery models: we supply engineered trusses, supervise crane setup, direct sequence assembly, verify alignment, and issue sign-off certificates — while your contractor manages foundations, concrete work, and roofing.
