For over two decades, BRILLIANCE has been a trusted name in the aluminum extrusion industry, delivering precision-engineered square profile aluminum solutions to clients worldwide. Our expertise spans architectural, industrial, and specialized sectors. Every profile we manufacture meets high standards for quality, durability, and performance. Whether you need materials for construction, machinery frameworks, or custom equipment, this guide explains everything about square profile aluminum—and why BRILLIANCE is your ideal partner.
1. The Value of Square Profile Aluminum in Modern Industry
Square profile aluminum is a key material in today’s manufacturing and design. Its symmetrical cross‑section provides uniform strength in all directions. That makes it better than round or rectangular profiles for applications that need both structural stability and visual balance. From heavy industrial frames to architectural facades, square aluminum combines light weight with outstanding durability.
With over 21 years of experience, BRILLIANCE has perfected aluminum extrusion. Our square profile aluminum products fit seamlessly into many industries—construction, automotive, renewable energy, medical equipment, and more. We don’t just supply profiles; we deliver engineered solutions built around your project requirements.
2. Technical Specifications of Square Profile Aluminum
Knowing the technical details helps you choose the right profile. Below are the critical parameters that affect performance and suitability for different applications.
| Parameter | Specifications & Insights |
|---|---|
| Alloy Options | 6063-T5/T6: Best for architectural uses where surface finish and corrosion resistance matter. Ideal for window frames, curtain walls, and decorative trims. 6061-T6: Offers higher strength and excellent weldability. Perfect for structural parts, machinery frames, and automotive components. 7075-T6: High‑strength alloy used in aerospace and demanding industrial applications. |
| Common Sizes | Standard dimensions range from 10x10mm to 200x200mm, with wall thickness from 1mm to 10mm. We specialize in custom sizes to match unique project designs. |
| Surface Treatments | Mill Finish: Raw aluminum for further processing. Anodized: Improves corrosion resistance and gives a durable, metallic finish. Available in silver, bronze, black, and custom colors. Powder Coated: Offers a wide range of RAL/Pantone colors for both aesthetic and protective needs. Wood Grain: Provides a natural wood appearance for architectural accents. |
| Tolerances | We follow GB/T 5237 and EN 755 standards and achieve precision tolerances as tight as ±0.05 mm. This ensures consistency for high‑precision assemblies. |

5. Frequently Asked Questions (FAQ)
What is the minimum order quantity (MOQ) for custom square aluminum profiles?
Our standard MOQ is 500 kg per profile. However, we understand the importance of prototyping. We offer flexible, low‑volume trial runs to help clients validate designs before scaling up.
Can you match specific colors or surface finishes?
Yes. We provide custom anodizing and powder coating to match any RAL or Pantone color. For architectural projects, our wood grain finish reproduces natural timber beautifully.
How do you ensure product quality and consistency?
Quality is our priority. We are ISO 9001:2015 certified and carry out rigorous in‑process inspections. Each shipment comes with a material test certificate, and we can arrange third‑party inspections (like SGS) at your request.
What are your typical lead times for production?
For standard extrusion, lead time is about 15‑20 days. Surface finishing adds another 7‑10 days. Our supply chain in Guangdong and Shanghai helps us maintain on‑time delivery.
Do you provide technical support for design or installation?
Yes. Our engineering team offers design consultations, load‑bearing calculations, and installation guidance to help your project succeed from start to finish.
