From Raw SS Tube to Finished Product — We Supply Both
From balcony railings to bathroom accessories, our ASTM A554 tubes are the raw material behind some of the most demanding architectural and decorative projects worldwide. E-Stainless supplies the right welded tube — right grade, right finish, right tolerance.
And if you need finished products like door pull handles, handrails or railing systems, our parent company E-PAI also manufactures finished architectural products directly.

Why Global Buyers Trust E-Stainless
We don’t just make stainless steel tubes — we use them. Here’s what makes the difference.
Backed by E-PAI Group
E-Stainless is a subsidiary of E-PAI Metal Products Co., Ltd., a manufacturer with 28 years of experience producing stainless steel architectural hardware including door pull handles, handrails, and railing systems.
We don’t just make ss tubes — we use them. That means every tube we produce is built to the real tolerances that fabrication and assembly actually demand.
Raw Materials from China's Top 3 Steel Mills
All our stainless steel comes from TISCO, Baosteel, and Tsingshan — three of China’s most recognized producers. Every coil is traceable and supplied with a full Mill Test Certificate (MTC). You know exactly what grade and composition you’re getting, batch after batch.
100% Bendable Welds — No Cracking
Our tubes pass a full 180° bend test without cracking or weld separation. This matters most for railing and handrail fabricators who bend tubes on-site or in the shop.
60 Automated Production Lines for Large-Volume Orders
With 60 automated lines running continuously, we can handle high-volume orders without compromising lead time or dimensional consistency.
Micron-Level Dimensional Tolerance
We hold wall thickness to ±0.02mm and outer diameter to ±0.15mm across every batch. Tubes fit standard fittings without adjustment, and your finished products stay consistent from the first piece to the last.
Custom Cut-to-Length Service
We cut tubes to your specified length before shipping, reducing your workshop preparation time and material waste. Just tell us your required length — we handle the rest.
Tubes and Fittings from One Supplier
We supply a full range of matching fittings — elbows, couplings, tees, flanges, and railing brackets — made from the same grade of stainless steel as your tubes. Same material, same finish, same supplier. No sourcing gap, no mismatched appearance.

Case Stories
From single fabrication orders to large-scale construction supply, we handle every shipment with care.
Architectural Railing Project / USA
A fabricator sourcing mirror-finish round tubes for a high-end residential railing installation. Each tube was individually wrapped and packed in custom wooden crates to prevent surface contact during ocean freight. The client received scratch-free tubes ready for immediate installation upon arrival.
Premium Decorative Tube Order / Germany
A European distributor ordering polished tubes for interior decorative applications. Tubes were packed using individual paper tube sleeves, providing full surface protection while keeping shipment weight low. This packaging method is widely used for finish-sensitive orders destined for European markets.
Large-Scale Construction Supply / Australia
A contractor placing a bulk order of structural tubes for a commercial building project. Tubes were strapped into large bundles optimized for forklift and crane unloading at the job site. This method maximizes container loading efficiency and reduces overall freight cost for high-volume orders.
Railing Fabrication Project / Saudi Arabia
A fabrication workshop ordering mixed-size tubes across multiple railing projects. Tubes were packed into smaller bundles by size and specification, making on-site sorting and distribution straightforward. This approach reduces handling time and keeps different specs clearly separated throughout the project.

Quality You Can Verify at Every Stage
Every tube we ship passes through a structured quality control process — from raw material intake to final inspection before loading. Nothing leaves our facility without meeting spec.
ISO 9001:2015 Certified Manufacturing
Our entire production system operates under ISO 9001:2015 certification, ensuring consistent quality standards are applied across every batch and every order.
Multi-Stage Production Testing
Every tube undergoes spectrometer analysis, flaring, indentation, flanging, and eddy current testing throughout the production process to verify material composition, weld integrity, and dimensional accuracy.
Pre-Shipment Inspection
Before loading, each order is inspected for wall thickness, surface finish, and dimensional compliance. Your tubes are confirmed to spec before they leave our facility.
