What is the anti-rust treatment for steel structure?

We use a 12-head shot blasting machine to grade S2.5, followed by epoxy zinc rich primer, epoxy cloud iron intermediate paint, and epoxy polyester topcoat.

Can we construct steel framed houses on sea shores or mountains?

Yes, steel systems are highly resistant to rust via galvanization and can be safely used in mountainous or seaside areas with intense salt.

How do we cooperate on a certain project?

Send project details, requirements, and design proposals. We will then make a quotation, and upon agreement, we finalize the deal.

Is your price competitive with other companies?

Our objective is to offer the best price for the same quality or the best quality for the same price, helping you reduce costs.

How to get an accurate quotation?

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

Is a steel structure better than concrete?

Steel handles tensile stresses better, has a superior strength-to-weight ratio, is easier to transport, and constructs faster than concrete.

What are building regulations in China?

Buildings must follow General Specification for Steel Structures GB 55006-2021. We comply with all regulations to ensure a safe working environment.

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.
