Infrastructure
Sustainable construction
Renewable energy projects
Supplier identification
Production-route information
Carbon-related data where available
Environmental documentation where available
Product and material traceability
CBAM-related supplier information
Specific carbon data, environmental documentation and production methods depend on the selected manufacturer and product.
Additional Steel Sourcing
Our core focus is steel pipes and structural tubes. However, some international projects require a broader range of steel products.
Through our China supplier network, we can also support sourcing for selected products outside our core portfolio.
Seamless Steel Pipe
For high-pressure, high-temperature, mechanical and industrial applications.
LSAW & SSAW Steel Pipe
For large-diameter water transmission, piling, infrastructure and pipeline projects.
Stainless Steel Pipe & Tube
Including commonly requested grades such as 304, 304L, 316 and 316L.
Alloy Steel Products
Including alloy steel pipes and selected high-performance materials for demanding industrial applications.
Steel Conduit
EMT, IMC and rigid steel conduit for electrical and infrastructure applications.
Other Steel Materials
Selected steel plates, coils, structural products and other industrial steel materials can be sourced according to project requirements.
Send us your specification, drawing, RFQ or product requirements.
We will review the project and identify suitable supply options in China.
China Steel Sourcing Services
International steel procurement involves more than finding a competitive price.
We help buyers coordinate key steps between the purchasing team, manufacturing partner, inspection company and logistics provider.
01 — Requirement Review
We review your product specifications, standards, dimensions, quantity, application and destination.
02 — Supplier Matching
We identify suitable manufacturing partners based on product capability, quality requirements, production capacity and commercial conditions.
03 — Technical Confirmation
We coordinate specifications, drawings, material grades, tolerances, coatings and other technical requirements before production.
04 — Quotation
We prepare a quotation based on the confirmed product requirements and agreed commercial terms.
05 — Sample & Production
Where required, samples can be arranged for verification before bulk production.
06 — Quality Inspection
