Cut2Size Metals offers welded stainless steel square tubing in Type 304 with inside and outside radius corners, meaning the corners are not sharp. Type 304 stainless steel square tubing is known for its strength and corrosion resistance. Square tubing is commonly used for structural support, railings, and fencing and is measured using the outside diameter (OD) and wall thickness.

• Standard sizes & custom cuts: Stock tubing is 20 ft. and can be custom cut to any length.
• Tolerances: Our standard tolerance for custom cuts is +/- 1/16". If you need a tighter tolerance, call us!
• Volume discounts: Unit prices drop on most custom-cut products when you increase the quantities.

Alloys & Finishes

Alloys

304 Stainless Steel
Type 304 is the most commonly used stainless steel alloy. It stands out with its strong formability and excellent weldability. It can be easily roll-formed or bent to suit specific needs making it a top choice for various applications. 304 offers reliable corrosion resistance and performs well in both chemical and atmospheric conditions.

Characteristics of alloy 304:
Machinability = Fair
Corrosion Resistance = Good
Weldability = Excellent
Bending/Forming = Good
Magnetic = No

Common applications of alloy 304:

• Best general-purpose stainless steel and is suitable for a broad range of applications.
• Food processing equipment, including containers and conveyors.
• Kitchen appliances, such as sinks, cookware, countertops, and backsplashes.
• Architectural elements like railings and panels.
• Chemical processing equipment, including tanks and piping.
• Medical instruments and devices.

Finishes

What is a Mill Finish?
Mill finish means that items come to exactly as they are finished at the mill. All materials can have some surface scratches and may have a dull finish. If you want a certain type of finish on your material, give us a call at 812-429-1634.

How is Tubing Measured

Outside Diameter (OD) x Wall Thickness x Length
Stainless steel tube is measured by its outside diameter (OD) and its wall thickness. Tubing will keep the same OD no matter what the wall thickness is. Tubing has a tighter manufacturing tolerance than pipe.

Difference Between Pipe & Tube

Tubing vs Pipe. What's the Difference? Stainless Steel Tubing is generally associated with applications requiring precision and a smooth interior surface, while stainless steel pipe is typically used for conveying fluids or gases under pressure in industrial and plumbing applications. Pipe will always be round however tube can be round, square, or rectangular. The choice between tubing and pipe depends on the specific requirements of the application.
