Frequently Asked Questions

Q1: What is the standard wall thickness for your aluminum extrusions, and are there thicker options for heavy-duty applications?
A: The standard wall thickness for most profiles in our Windows & Doors series is 1.8mm. For heavy-duty applications requiring extra strength, we offer profiles with 2.2mm and 2.5mm wall thickness, such as the MK902-MK902 and MK1051 series.

Q2: Can you provide customized profile designs and surface finishes for my project?
A: Yes, we specialize in OEM/ODM services. We maintain a comprehensive mold library and can develop exclusive profile designs to your specifications. Available surface treatments include anodizing (silver, bronze, champagne, black), powder coating (all RAL colors), wood grain, electrophoresis, and PVDF fluorocarbon.

Q3: What are your minimum order quantities and typical lead times for wholesale orders?
A: We offer flexible MOQ based on order requirements. As a factory-direct manufacturer with an annual capacity exceeding 60,000 tons, we can handle both large wholesale orders and smaller custom projects.
