Product Introduction

Stainless Steel Square Tube is a welded hollow steel section manufactured from stainless steel strip and formed into a uniform square profile. Combining corrosion resistance, structural stability, and a clean surface appearance, it is widely used in architectural metalwork, industrial equipment frames, protective railings, and decorative structures.

MGTSP supplies stainless steel square tubes in grades including 304, 316, and 316L, with options for different dimensions, wall thicknesses, and surface finishes. The square profile provides flat surfaces for fabrication and installation, while the stainless steel construction helps maintain durability in environments where corrosion resistance is important.

For international projects, material grades, dimensional standards, and surface requirements can be specified according to the intended application.

Key Features

1. Corrosion-Resistant Stainless Steel

Available in 304, 316, and 316L stainless steel grades for applications requiring resistance to moisture and various corrosive environments. Material selection should consider the actual operating conditions.

2. Uniform Square Hollow Profile

The regular square section and consistent wall thickness support structural fabrication, equipment framing, and metal assembly.

3. Good Fabrication Performance

Suitable for cutting, drilling, bending, and welding when the appropriate fabrication methods are selected for the material grade and wall thickness.

4. Multiple Surface Finish Options

Brushed and bright polished finishes are available for architectural, industrial, and decorative projects with different appearance requirements.

5. Flexible Dimensional Options

A range of square section sizes and wall thicknesses can be specified to meet project requirements, with cut-to-length options available.

Frequently Asked Questions

What is the difference between 304 and 316 stainless steel square tube?

Both are commonly used stainless steel grades. Grade 316 contains molybdenum and generally offers improved resistance to certain chloride-containing environments compared with 304. The appropriate grade depends on the intended exposure and service conditions.

What sizes are available for stainless steel square tubes?

The current product range lists side lengths from 10 mm to 200 mm, with different wall thickness options. Please confirm the required dimensions and availability before ordering.

Can stainless steel square tubes be supplied with polished surfaces?

Brushed and bright polished finishes are listed as available options. Surface finish requirements should be confirmed during quotation.

What information is needed when ordering?

Please specify material grade, side length, wall thickness, tube length, surface finish, quantity, and any applicable project standard.
