How do I get an accurate quotation?

Please provide dimensions, door/window details, local climate data (wind/snow/seismic), insulation materials, crane requirements, and any drawings or specific requirements.

Can steel structures be built in seaside or mountainous areas?

Yes, steel systems are highly resistant to rust via galvanization, making them safe for seaside areas with intense salt or mountainous regions.

What certifications and standards do you follow?

We comply with General Specification for Steel Structures GB 55006-2021 and other standards like GB and ASTM, ensuring high quality and safety.

AI-Powered supplier vetting

SummaryZhejiang Huachuang Heavy Industry Co., Ltd. is a China-based manufacturer/factory in Zhejiang serving construction and decoration markets. The supplier reports defined metal-structure, equipment, and metal-material business activities, documented R&D processes, CAD/SolidWorks/UG capabilities, broad customization options, and stated production capacities for steel, color steel plates, and floor panels. It has inventory capability, valid manufacturing contracts with related subcontractors, standardized finished-product inspection, and documented procedures for corrective actions and complaint handling. It provides OEM services for popular brands and has export rights, although exports represent only 1%–10% of sales. No SDK, overseas warehouse, or overseas showroom is available. Financial information is limited to reporting years and does not establish financial strength. No explicit certification information or specific customer cases is provided.

Supplier typeThe supplier is identified as a manufacturer/factory and a limited company based in Zhejiang, China. Its stated activities cover metal-structure manufacturing, equipment-related activities, metal-material sales/manufacturing, and construction and decoration trade, indicating direct manufacturing capability rather than a trading-only profile.

After-Sales capabilityTechnology engineers provide technical support for production and after-sales service. The supplier also reports clear, followed procedures and records for corrective and preventive actions and customer complaints, supporting a structured after-sales process; however, no response-time or service-network metrics are provided.

R&D capabilityThe supplier reports R&D engineers responsible for confirming customer requests and technical support, maintains design input/output, review, verification, and validation documents for audit, and uses CAD, SolidWorks, and UG. It also explicitly lacks an available SDK, so software-integration capability is limited based on the provided evidence.

Production capacityThe supplier reports annual capacities of 40,000 tons of light and heavy steel, 20,000 tons of CZ steel, 300,000 square meters of color steel plates, and 200,000 square meters of floor panels. It has in-stock capability and valid contracts with each related subcontractor, while its stated business scope includes manufacturing activities, supporting a substantial production profile.

Customization capabilityThe supplier supports customization from samples, designs, full customization, minor customization, and flexible customization. Its engineers confirm customer requirements and provide production-related technical support, indicating broad customer-specific design and manufacturing adaptability.

Product Q&A

Q:Can I visit your factory before ordering?

Yes, welcome to visit. Fly to Shanghai, Hangzhou, or Wenzhou airports, take a high-speed train to Lishui railway station, and we will pick you up and provide hotel booking services.

Q:Do you provide installation services?

Yes, we send engineers and construction workers to supervise installation. You need to pay the professional installation cost in advance according to the confirmed payment terms.

Q:What is the expected service life of the structure?

The main structure has a designed life of at least 50-100 years per GB standard. The PE coating on the roof lasts 10-25 years, while FRP sheets last 8-15 years.

Q:What anti-rust treatment is applied to the steel?

We use 12-head large shot blasting machines for S2.5 grade cleaning, followed by epoxy zinc-rich primer, epoxy cloud iron intermediate paint, and epoxy polyester topcoat.

Q:Is steel structure better than concrete?

Steel structures handle tensile stresses better, are lighter, faster to construct, and easier to transport. Concrete handles compression well but requires reinforcement for tensile strength.
