Product Description

Key Standards & Material Specifications

Welded square pipes are divided into structural framing, mechanical components, and decorative/architectural tubing based on international standards:

Standard / Grade	Type	Key Features & Applications	Yield Strength (min)
ASTM A500 (Gr. B & C)	Structural	Cold-formed welded tubing for bridges, building frames, trailer chassis	Grade B: 46 ksi (315 MPa) Grade C: 50 ksi (345 MPa)
ASTM A513 (Type 1 & 2)	Mechanical	ERW carbon steel tubing for furniture, automotive frames, appliances	Depends on temper / carbon content
EN 10219 / EN 10210	Structural	European standard for cold-formed (10219) or hot-finished (10210) hollow sections	S235JRH to S355J2H (235355 MPa)
ASTM A554	Stainless	Ornamental welded square tubing (304/304L, 316/316L) for handrails & architectural trim	As-welded or polished

Manufacturing Process Options

Continuous Cold Roll Forming (Standard ERW):

A continuous steel strip is gradually bent into a round tube, high-frequency welded along the seam, and then immediately passed through sizing rolls that square the sides and form the corner radii.
Direct-to-Square Forming:

The strip is formed directly into a square cross-section before welding. This reduces stress concentrations at the corners and allows for tighter wall thickness consistency across the profile.
Hot Finishing (e.g., EN 10210):

Cold-formed ERW square tubes are reheated into the austenitic temperature range to relieve internal cold-working stresses. This produces consistent mechanical properties across the flat walls and the corners, making them suitable for high-dynamic-load or low-temperature structural applications.

Precision Engineered for Versatility

Produced using advanced ERW technology, our stainless steel square pipes offer tight tolerance control (within 0.5 mm) and consistent hardness. Whether your application demands heightened structural integrity or a polished visual finish, these pipes are suited to a wide range of uses including building frameworks, architectural features, and custom furniture.

Superior Surface Quality and Corrosion Resistance

Each pipe is thoroughly cleaned to remove scale and oil from the inside and polished on the outside, ensuring both hygienic and aesthetic qualities. The corrosion resistance varies by grade, but all options provide excellent durability in different environmental conditions, making them suitable for both interior and exterior projects.

FAQ's of Welded Square Pipe:

Q: How are the welded square pipes manufactured and what standards do they meet?

A: These pipes are produced using the Electric Resistance Welded (ERW) method, which ensures uniform wall thickness and precise dimensional control. They are manufactured according to ASTM A554, AISI, DIN, and EN standards, guaranteeing reliable quality for structural and architectural applications.

Q: What is the available range of sizes and thicknesses for these pipes?

A: Our welded square pipes are available in outer diameters from 20 mm to 150 mm and thicknesses ranging from 1 mm to 6 mm. Standard lengths are 3 meters and 6 meters, but custom lengths can be provided as per customer requirements.

Q: How can customers specify end finish and surface requirements?

A: Customers may choose from plain, deburred, or custom end finishes, and all pipes are supplied with a polished exterior and a clean, scale-free interior. Special finishes or surface treatments can also be discussed to suit unique project needs.

Q: Where are these welded square pipes typically used?

A: They are widely utilized in construction, building structures, architectural frameworks, fabrication projects, and furniture manufacturing due to their strength, durability, and visual appeal.

Q: What are the packaging and delivery options for these pipes?

A: Pipes are packaged according to customer preference and project size, using secure plastic wrapping or wooden cases to provide protection during transportation and delivery.

Q: What are the benefits of choosing stainless steel welded square pipes from your company?

A: Clients benefit from excellent corrosion resistance, strength, customizable sizes and finishes, and reliable performance across various industries. Our products also assure ease of welding and installation, resulting in versatile, long-term solutions for demanding environments.
