4″ X 4″ X 1/4″ Galvanized Angle

This galvanized steel angle (L-shaped angle iron) has equal legs of 4 in (102 mm) x 4 in (102 mm) and a thickness of 1/4 in (6.3 mm). The zinc coating protects the steel from rust, making it suitable for exterior framing, supports and fabrication where bare steel would corrode quickly.

Angle is one of the most versatile structural shapes. Its 90-degree profile resists bending in two directions and provides a flat surface on each leg for bolting, welding and mounting. It is used for frames, braces, brackets, shelf supports, lintels, edge protection, trims and countless general fabrication jobs.

Key Features

  • Equal legs: 4 in (102 mm) x 4 in (102 mm)
  • Thickness: 1/4 in (6.3 mm)
  • Galvanized zinc coating for corrosion resistance
  • Strong, rigid 90-degree profile
  • Easy to cut, drill, weld and bolt

Specifications

  • Material: galvanized (zinc-coated) carbon steel
  • Shape: equal-leg angle
  • Leg size: 4 in (102 mm) x 4 in (102 mm)
  • Thickness: 1/4 in (6.3 mm)

Typical Applications

  • Structural frames, braces and supports
  • Equipment and machine bases
  • Shelving, racks and brackets
  • Lintels, edging and trim
  • Truck, trailer and agricultural fabrication
  • Fence, gate and railing construction

Selection Guide

Larger leg sizes and thicker steel increase stiffness and load capacity. Choose the section based on your span, load and connection details, and confirm design values with your engineer. Galvanized steel is carbon steel protected by a zinc coating. The zinc acts as a barrier against moisture and oxygen and also protects the steel sacrificially at small scratches and cut edges, which is why galvanized material is a long-lasting choice for outdoor, damp and industrial settings.

Fabrication

Galvanized steel can be cut, drilled, welded and fastened with standard metalworking tools. Zinc fumes are released when galvanized steel is welded, so work in a well-ventilated area, use appropriate respiratory protection and grind away the coating near the weld zone where possible. After cutting, welding or drilling, touch up exposed steel with a zinc-rich cold galvanizing compound to restore corrosion protection.

Storage and Handling

Handle and store the material off the ground, on dunnage, in a dry and ventilated area. Avoid stacking wet material tightly, as trapped moisture can cause white storage stain (harmless zinc oxide). Dimensions, weights and finish appearance (spangle) may vary slightly between production lots. Please verify critical dimensions and load requirements with your engineer before purchase; this product description is for general guidance and is not a substitute for engineering design.

Frequently Asked Questions

Are the legs equal?
Yes, both legs are the same size.

Can I weld it?
Yes, with appropriate ventilation and coating-removal precautions.
