- Fire resistance: 1-3 hours.

5. Fabrication & Installation Parameters

Fabrication Tolerance
- Component length: ±2 mm/6 m.
- Bolt hole spacing: ±1.5 mm.
Installation Requirements
- Verticality deviation: ≤H/1000 and ≤25 mm (total height).
- Weld quality: Grade I (full penetration) or Grade II (partial penetration).

6. Applications

Building Types: Offices, hotels, apartments, commercial complexes.
Typical Height: 6-40 stories (20-150 m).
Economic Spans: 6-12 m (main beams), 3-6 m (secondary beams).

We offer one-stop service from design, manufacture, delivery to installation and after-service.

Frequently Asked Questions

Q1. How can I get a quotation for my project?

A: If you already have structural drawings, please share them with us, and we will perform a quotation based on them. Alternatively, if you do not have drawings, you can provide us with key parameters (such as location, dimensions, local wind/snow loads, seismic requirements, and insulation options), and our design team will create a preliminary layout and quote for you.

Q2. Can we arrange a visit to your production plant before ordering?

A: Absolutely. You are welcome to visit our fabrication facilities to inspect our production capacity and quality standards. Please contact our service team in advance to schedule your tour, and we will be happy to arrange airport pick-up services.

Q3. Is your pricing competitive compared to other steel structure manufacturers?

A: Our objective is to deliver the absolute best cost-to-quality ratio. We optimize every link of the supply chain and rely on raw material clusters to reduce production costs. This ensures you get high-end, certified steel structures at highly competitive rates.

Q4. Do you support third-party container loading inspections?

A: Yes, we welcome third-party inspections. You may send an independent inspector to check product specifications during the production process, and oversee container loading before shipment to ensure compliance with global transport standards.

Q5. What designing software systems do you use for engineering?

A: We design complete structural solution drawings using professional engineering software, including AutoCAD, PKPM, 3D3S, and Tekla Structures (X-Steel). This allows us to design complex industrial and commercial buildings like multi-story offices, high-rises, logistics warehouses, and hangers.

Q6. What is the typical delivery timeline?

A: The overall delivery time depends strictly on the order volume and design complexity. Generally, we complete fabrication and deliver to the nearest domestic seaport in China within 30 days after receiving the initial project deposit.
