FAQ
Q1: Can you customize the aluminum profile shape and dimensions?
A: Yes, we offer full customization based on your drawings or specific requirements. We support custom shapes, wall thicknesses, lengths, surface finishes, and even hole positioning. Just send us your CAD files or samples.
Q2: What surface treatments are available?
A: We provide a wide range of finishes including anodizing (natural, black, bronze, etc.), powder coating, electrophoresis, sandblasting, polishing, and brushing. Surface treatment enhances corrosion resistance and appearance.
Q3: What is your MOQ (Minimum Order Quantity)?
A: Our standard MOQ is 500kg per profile. However, for new customers or special projects, we are flexible and can accept smaller trial orders.
Q4: Do you offer OEM and ODM services?
A: Absolutely. We support both OEM and ODM. We can produce based on your designs and also provide design support if you only have an idea or sample.
Q5: How do you ensure product quality?
A: We have a strict QC system that includes raw material inspection, extrusion tolerance checks, surface finish testing, and final packaging control. Our factory is ISO 9001 certified and products meet SGS or CE standards upon request.
Q6: What is the lead time for orders?
A: Normally, production takes 10–15 working days after confirmation of the drawing and receipt of the deposit. For urgent orders or repeat products, the lead time may be shorter.
Q7: Do you offer cutting, drilling, or machining services?
A: Yes, we provide CNC machining, cutting to length, drilling, tapping, and welding services. This saves you time and cost on secondary processing.
Q8: What kind of packaging do you use for export?
A: Our aluminum profiles are protected with plastic film or paper between each piece, bundled with foam or EPE, and packed in strong export cartons or wooden pallets to prevent damage during transit.
Q9: Can I get a free sample?
A: Yes, small samples (less than 30cm) of standard profiles are available for free. For custom profiles, we may charge mold costs, but those can be refunded upon bulk order confirmation.
Q10: What industries are your aluminum profiles used in?
A: Our profiles are widely used in solar mounting systems, industrial automation, tent structures, furniture frames, construction, windows & doors, and transportation. We support various custom applications.
Factory Introduction
|
Factory
As a professional aluminum profile manufacturer, we are committed to delivering high-precision, customized extrusions for industrial, construction, and solar applications. From extrusion to packaging and shipping, every step is carefully managed under strict quality control to ensure consistent performance and timely delivery.
|
Workshop
Extrusion
Mold Design & Fabrication: Precision steel molds are designed according to cross-sectional drawings
Extrusion Process: Preheated billets are pushed through the die to form the desired profile shape
Length Control: Standard extrusions are typically 6 meters long
Cooling & Straightening: Profiles are cooled immediately, then pulled and straightened to maintain shape and dimensional accuracy
Tempering
Purpose: Enhances mechanical strength and hardness
Common Tempers:
T5: Air cooling + artificial aging
T6: Water quenching + artificial aging
Key Control Factors: Temperature, duration, and cooling speed must be precisely managed
Surface Finishing
Anodizing，Electrophoretic Coating，Powder Coating，Wood Grain Transfer，Polishing / Brushing
CNC Machining
Typical Operations: Drilling, tapping, cutting, milling, punching, bending, etc.
Machinery: CNC machines, punch presses, cutting saws, tapping machines
Customization: Fully adaptable to client’s drawings and complex assembly needs
