1050 Aluminum Tread Plate 5 Bar Mill Finish: The Ultimate Guide to Standard Diamond Plate
When you need a classic, highly effective, and economical slip-resistant flooring solution, 1050 aluminum tread plate with a 5 bar mill finish is the industry-standard choice. Characterized by its distinctive raised diamond pattern, this material offers an unbeatable combination of safety, durability, and value for a vast range of industrial and commercial applications. At Gwangyang Aluminum (GYAL), we manufacture this essential product to the highest international standards, providing a reliable and cost-effective supply for partners across North America and beyond.
What is 1050 5 Bar Diamond Plate?
This specification defines a precise and popular product:
1050 Alloy: A commercially pure aluminum alloy (minimum 99.5% aluminum). It is known for its excellent corrosion resistance, high formability, ease of welding, and outstanding thermal/electrical conductivity.
5 Bar Pattern: Also known as the “diamond plate” pattern, it features a grid of raised diamonds or lines. The “5 bar” refers to the pattern’s design, providing superior multi-directional slip resistance and a classic industrial aesthetic.
Mill Finish: This is the natural, non-coated surface of the aluminum as it comes from the rolling mill. It presents a clean, metallic look and is ready for use or can be painted/powder-coated if desired.

Key Advantages of 1050 5 Bar Mill Finish Tread Plate
Choosing this specific combination delivers a host of practical and financial benefits:
Optimal Slip Resistance: The 5 bar diamond pattern provides maximum traction from all angles, making it the go-to choice for safety-critical areas like stairs, ramps, and work platforms.
Lightweight & Easy to Handle: 1050 aluminum is one of the lightest industrial metals, simplifying installation and reducing structural load. Its softness also makes it exceptionally easy to cut, drill, and form on-site.
Excellent Corrosion Resistance: The high aluminum content ensures strong resistance to rust and atmospheric corrosion, ideal for indoor use and many sheltered outdoor environments.
Superb Value for Money: As the most economical aluminum alloy commonly used for tread plate, and requiring no additional finishing, it delivers exceptional performance at a highly competitive price point.
Easy to Clean & Maintain: The raised pattern helps channel liquids and debris, while the non-porous metal surface can be easily wiped or washed down.
Primary Applications: Where This Product Excels
GYAL's 1050 5 bar mill finish tread plate is engineered for versatility across multiple sectors:
Industrial Flooring & Walkways: The standard for factory mezzanines, catwalks, machine platforms, and areas where oil or water may be present.
Transportation: Extensively used in truck and trailer flooring (especially for dry freight), RV steps, and utility vehicle bed liners.
Stair Treads & Safety Ramps: Provides OSHA-compliant slip resistance for indoor and outdoor stairs, loading docks, and access ramps.
Architectural & Functional Uses: Popular for decorative wall panels, kick plates, protective equipment coverings, and durable workbench surfaces.
5 Bar vs. 1 Bar Pattern: Which is Right for You?
While both offer slip resistance, the 5 bar (diamond) pattern is generally preferred for:
Areas where traffic approaches from multiple directions.
Environments with liquids, where the pattern helps with drainage.
Applications demanding the highest level of safety traction.
The 1 bar (linear) pattern is often chosen for easier cleaning (debris doesn’t get lodged in diamonds) or for a specific aesthetic.
