OEM Powder Coating & Painted Steel Tube Manufacturer

Painted Steel Tube Factory

Painted steel tube is essentially a steel tube (which can be either seamless or welded) that has a layer of paint applied to its exterior surface. This paint coating acts as a protective barrier against rust, corrosion, and wear, while also offering aesthetic appeal or enabling color-coding for specific applications. The steel itself provides the structural strength, and the paint enhances its longevity and appearance.

Key Features

Product Specifications

We offer a comprehensive range of painted steel tubes, designed to meet the rigorous demands of the construction industry.

Base Steel Types: Typically carbon steel (e.g., ASTM A500, ASTM A53) for structural and general construction uses, offering excellent weldability and strength.

Shapes: Most commonly supplied as round, square, and rectangular hollow sections (HSS), allowing for diverse architectural and structural designs.

Outer Diameter (OD) / Side Dimensions:

• Round Tubes: From 0.5 inches (12.7mm) for architectural details to 24 inches (610mm) or larger for heavy structural columns.
• Square/Rectangular Tubes: Available in side dimensions from 0.5x0.5 inches (12.7x12.7mm) up to 20x20 inches (508x508mm) or larger, catering to various load-bearing and design requirements.

Wall Thickness: Ranging from 1.0mm (0.04 inches) for lighter-duty or decorative applications up to 25mm (1 inch) or more for primary structural elements and heavy-duty frameworks.

Length: Standard lengths commonly include 6 meters (20 feet) and 12 meters (40 feet). Custom cut-to-length services are often available to minimize waste and streamline fabrication on site.

Paint Types:

• Primer Coats: Often red oxide or zinc-rich primers for foundational corrosion resistance.
• Topcoats: Epoxies, polyurethanes, alkyds, or acrylics are common, chosen based on required durability, chemical resistance, UV stability, and desired finish (matte, semi-gloss, gloss). Custom color matching to RAL or Pantone codes is frequently offered.
