Stainless steel pipe,
specified properly.
A factory-led supplier of 201, 304 and 316 stainless steel pipe, tube, sheet and custom project orders — quoted accurately and packed for export.
Three grades cover most of what you specify.
Start from the service environment. We help you weigh 201, 304 and 316 — and their L variants — so you neither over-specify nor under-specify the line.
General-purpose
Balanced corrosion resistance, weldability and availability — the default for construction, water, food equipment and general industry.
Corrosion-grade
Molybdenum-bearing, with better resistance to pitting, crevice and chloride attack — for chemical, coastal, marine and water-treatment service.
Cost-sensitive
Low-nickel, high-manganese and economical — for indoor decoration, furniture, handrails and general structures in controlled, dry environments.
Pipe, tube, sheet & custom supply.
Seven product families across the full ZAIHUI grade range. Select by form and service, then send the spec for a quotation.
304 Industrial Pipe
General-purpose austenitic pipe with balanced corrosion resistance and weldability.
316 Industrial Pipe
Molybdenum-bearing pipe for chloride, chemical, coastal and water-treatment service.
201 Industrial Pipe
Low-nickel, cost-sensitive pipe for indoor decorative and structural work.
Mechanical Structural Tube
Round, square and rectangular tubing for frames, supports and fabrication.
Industrial Fluid Pipe
Pipe for process, utility and water lines — grade matched to the medium.
Stainless Steel Sheet & Plate
Sheet and plate across the full grade range, finished and cut to the project.
Custom Industrial Pipe
Drawing-based supply with confirmed grade, size, finish, inspection and export packing.
A supplier built around the spec.
Manufacturer-direct
With 130+ production lines, you buy direct from the factory rather than a middleman — grade, dimensions and finish kept under one roof.
Quote-ready, not salesy
We ask for grade, OD, wall thickness, standard and finish up front, so the conversation stays technical from first message to shipment.
Export-ready
28 direct branches and 500+ distributors. Inspection files, batch marks and export packing supported so orders arrive ready to use.
Where ZAIHUI stainless steel goes to work.
Construction & architecture
Handrails, railings, façade trims and decorative tube — 304 for general exterior, 201 for controlled indoor.
Fabrication & furniture
Frames, supports, signage and equipment parts in structural tube and brushed or polished finishes.
Fluid & process
Water treatment, process and utility lines — 304 vs 316/316L chosen for the chloride and chemical load.
Distribution & trade
Wholesale, replenishment and export stock with repeatable specs and material certificates.
From application to delivered price, in three steps.
A quote path that feels prepared, not pushy — so the offer you receive is one you can hand to procurement.
Start with application
Municipal works, railings, fabrication or distributor stock each set different priorities for grade and finish.
Confirm the standard
GB, ASTM/ASME, JIS, DIN or your drawings — aligned before production so the spec is unambiguous.
Quote with logistics
Quantity, packing, freight and delivery date folded into a single, export-ready quotation.
Notes for stainless steel buyers.
Practical guidance on grade selection and specification — written before you send an RFQ.
304 vs 316: which do you need?
When the molybdenum in 316 earns its place over 304 — and where 304 is the right, cost-effective call.
