Premium solutions fabricated in our advanced manufacturing facility according to strict global industry standards.
Aluminum square pipes (tubes) are structural pillars across global industrial infrastructure. At Foshan Golden Source Precision Manufacturing Co., Ltd., we recognize that engineering challenges call for more than just stock dimension products. Customized wall thicknesses, precise cross-sectional dimensions, chemical purity variations, and temper optimizations allow engineering managers to push boundaries in structural strength and weight reduction.
Whether your project requires high tensile strength for high-speed rail mounting structures, micro-millimeter precision for 3C electronics assembly, or corrosion resistance for offshore solar bracket installations, our advanced material engineering handles it. In-house smelting capabilities allow for trace composition calibration, yielding extrusion profiles with excellent physical properties and optimal alloy purity.
Choosing the correct aluminum alloy series and heat-treatment (temper) profile defines the overall tensile capacity, ductility, and corrosion resilience of the square pipe. Below is a professional reference guide for B2B engineering specifications:
| Alloy Series | Common Tempers | Yield Strength (MPa) | Tensile Strength (MPa) | Key Performance Applications |
|---|---|---|---|---|
| 6063 Aluminum | T5, T6, T66 | 110 - 200 | 150 - 240 | Architectural profiles, structural frames, window & door clips, furniture fixtures. Excellent surface finish capacity. |
| 6061 Aluminum | T6, T6511 | 240 - 275 | 290 - 310 | Heavy-duty structures, machine framing, brackets, logistics equipment, marine components, gate valves. |
| 7075 Aluminum | T6 | 430 - 505 | 510 - 570 | Aerospace, structural climbing poles, high-stress defense equipment, custom structural keys. Extreme strength-to-weight ratio. |
| 5XXX Alloy | H112, O | 80 - 150 | 190 - 260 | Corrosive environments, marine tankers, pressure vessels. Excellent weldability and salt-spray protection. |
Foshan is the undisputed heart of the global aluminum extrusion supply chain. Sourcing from our manufacturing facility in Foshan provides structural cost-efficiencies and technological advantages over competitors.
By refining raw aluminum ingots inside our own plant, we calibrate chemical compositions to eliminate impurities. This provides uniform structural properties and excellent anodizing color consistency across batches.
We provide a true "one-stop" solution: custom mold design and tooling manufacturing, high-pressure extrusion presses, high-speed multi-axis CNC machining centers, specialized welding, and modern surface finishing lines.
From natural anodizing, clear/satin finishes, electroplating, and powder coating to sandblasting and silkscreen printing, our finishing services adhere to strict industrial quality controls.
Established in 1991, Foshan Golden Source Precision Manufacturing Co., Ltd. is a leading manufacturer of high-strength, high-precision custom aluminum profiles, precise machining parts, welded structures, and assembled mechanical products. Covering an area of over 73,000 square meters, our facility delivers end-to-end efficiency. We produce custom solutions for hardware tools, 3C components, automotive framing, railway systems, architecture, furniture, and heavy-duty outdoor gear.
Our company is dedicated to sustainable manufacturing practices. We hold international standard system certifications including ISO9001 (Quality Management System), ISO14001 (Environmental Management System), and ISO45001 (Occupational Health & Safety). To support environmental goals in European and North American markets, we hold GRS (Global Recycled Standard) and RCV (Recycled Content Verification) certifications, ensuring full compliance with EU REACH and RoHS regulations.








Procurement structures for customized aluminum square pipes are based on raw material costs and manufacturing complexity. We calculate transparent pricing for B2B global purchasers using the following dynamic formula:
Unit Price (per piece) = [ (Raw Metal Weight × Ingot Price) + Extrusion Conversion Cost + Secondary Machining + Surface Treatment ] × Order Quantity
* Note: Ingot Price is pegged to daily rates on the London Metal Exchange (LME) or Shanghai Metal Exchange (SMM).Our integrated manufacturing system optimizes several elements of this formula. By handling smelting and tool design in-house, we reduce conversion costs and material waste. This allows us to supply high-quality materials at competitive price points.
| Outer Dimensions (mm) | Wall Thickness Range (mm) | Standard Length (m) | Straightness Tolerance (mm/m) | Dimensional Tolerance (mm) |
|---|---|---|---|---|
| 10 × 10 - 50 × 50 | 0.8 - 4.0 | 3.0 - 6.0 (Customizable) | ≤ 0.5 | ± 0.15 |
| 60 × 60 - 120 × 120 | 1.5 - 8.0 | 3.0 - 7.2 (Customizable) | ≤ 0.8 | ± 0.25 |
| 150 × 150 - 300 × 300 | 3.0 - 16.0 | 3.0 - 12.0 (Customizable) | ≤ 1.2 | ± 0.45 |
Custom aluminum square pipes are used across a wide range of industrial applications. Our products are engineered to perform in various demanding environments:
Customized 6061-T6 and 6063-T5 aluminum angles and square channels provide structural support for commercial building facades. These profiles deliver high wind-load resistance and durability against the elements.
High-strength profiles reduce structural weight while meeting crash safety requirements, improving fuel and energy efficiency in modern transportation systems.
Square tubes serve as structural framing and linear guide rails in automated warehouses, conveyor units, and solar mounting structures, offering easy assembly and alignment.

In-house smelting allows us to adjust trace chemical compositions to reach optimal physical characteristics, such as higher yield strength or enhanced ductility. This also ensures high chemical purity, which is critical for consistent anodizing, clean powder coating, and structural uniformity.
We hold ISO9001, ISO14001, and ISO45001 certifications. For markets with strict environmental limits, our RCV (Recycled Content Verification) and GRS (Global Recycled Standard) certifications ensure compliance with EU REACH and RoHS environmental standards.
Custom tooling costs are charged up front based on the dimensions and complexity of the cross-section. Ownership of the custom tooling is held by the buyer, and we store and maintain the molds in our facility. For volume orders that reach defined thresholds, we offer partial or full mold cost rebates.
For new custom designs, the mold fabrication and trial samples take 7 to 10 days. Once the sample is approved, bulk extrusion, CNC machining, and surface treatments are typically completed within 15 to 20 days, depending on order size and complexity.
Our standard extrusions conform to EN 755-9 and GB/T 5237 standards. For high-precision requirements, our advanced extrusion processes and CNC secondary machining centers can hold tolerances as tight as ±0.05mm.
