Products Description
Our Support Angle is an industrial-grade structural component designed for versatile mounting and bracing applications. Engineered from high-strength galvanized steel, it features precision-drilled holes and unique semi-circular punch-out tabs, making it the ideal choice for warehouse racking, machinery frames, and heavy-duty infrastructure support.
Key Features
Modular Punch-Out Technology
Features three integrated semi-circular punch-out sections, allowing for easy cable routing, component interlocking, or quick-release mounting without compromising the overall structural integrity.
Precision Engineering & Tolerances
Manufactured to strict industrial standards with a tolerance of +/- 0.05". All mounting holes are pre-punched at a uniform 0.59" diameter, ensuring seamless compatibility with standard bolt sets.
Double-Layer Corrosion Protection
Base material is high-quality galvanized steel. Furthermore, all cut or drilled edges are treated with cold galvanization, ensuring no area is left unprotected against rust, even in humid or outdoor environments.
Versatile L-Profile Design
The 2" x 2" x 1/8" L-shape profile provides superior resistance to bending and twisting, offering maximum load-bearing capacity for long-span supports.

FAQ (Frequently Asked Questions)
Q1: What is the purpose of the three "Punch-Out" sections in the center?
A: These sections are designed for modular flexibility. Depending on your installation needs, they can be treated as knock-outs for cable management, interlocking tabs for joining multiple sections, or mounting points for secondary components. Their precise spacing (1.50" apart) ensures compatibility with standard industrial racking systems.
Q2: Does cutting the 36" length affect the rust resistance of the product?
A: No, provided that the cut ends are treated correctly. Per our technical requirements, any cut, punched, or drilled areas are treated with cold galvanization. This ensures that the zinc protection remains continuous across the entire surface, leaving no exposed steel to prevent oxidation and rust.
Q3: Are the holes compatible with standard hardware?
A: Yes. All holes are punched at a uniform diameter of 0.59" (approx. 15mm). This is specifically designed to accommodate standard 1/2" or M12 bolts and hardware, which are the industry standard for structural bracing and support systems.
Q4: Can this Support Angle be customized to different lengths or hole patterns?
A: Absolutely. While this specific model is 36" long, we can manufacture custom lengths to your exact requirements. We also offer customization for hole diameters and spacing. Our production tolerance is maintained at a strict +/- 0.05" to ensure precision for large-scale assembly projects.
Q5: What is the load capacity of this 2" x 2" x 1/8" L-beam?
A: The load-bearing capacity depends on the span and the method of attachment. However, the 1/8" (3.17mm) thickness combined with the 2-inch L-profile provides high structural rigidity against bending.
