    Exceptional Cost-Effectiveness

    By focusing on the essential strengths of aluminum—durability, structural integrity, and sleek aesthetics—this solution delivers robust performance at a significantly lower investment compared to thermal break models. This allows you to allocate your budget more efficiently, potentially towards larger glazing areas or enhanced design features.

    Uncompromised Core Quality

    These products are engineered with high-grade aluminum profiles and precision manufacturing, ensuring long-lasting durability, excellent weather resistance (water and air infiltration), and reliable operation. They provide all the fundamental benefits of quality fenestration without the added cost for specialized thermal insulation you may not require.

    Streamlined Decision & Faster Delivery

    Choosing this standard, widely proven product line simplifies the specification process. It enables a quicker turnaround from order to production and installation, helping you keep your project timeline on track.

    💡 For projects where premium thermal performance is not critical, this non-thermal break series represents the most intelligent and value-driven choice. We are confident it will meet your functional and budgetary requirements perfectly.

    Frequently Asked Questions
    What aluminum alloy grades are used in your casement window profiles?
    Our casement window profiles are made from high-quality aluminum alloys including 6063, 6061, and 6060, available in T5 and T6 tempers. These grades are widely recognized for their excellent extrudability, surface finish quality, and structural strength, making them ideal for window and door applications.
    What surface treatment options are available for the aluminum profiles?
    We offer a wide range of surface treatments including mill finish, powder coating, anodizing, electrophoresis, fluorocarbon coating, and wood grain finish. Colors can be fully customized according to your project requirements or brand standards.
    Can the profiles be customized in terms of dimensions and length?
    Yes. Standard profile length is 6 meters, but custom lengths are available upon request. Wall thickness ranges from 0.8mm to 5.0mm. We also support OEM/ODM services including custom die development to meet your specific design requirements.
    What is the minimum order quantity (MOQ) and lead time?
    The minimum order quantity is 500kg. For die development and sample testing, lead time is typically 7–10 days. Mass production is completed within 15–30 days depending on order volume and complexity.
    What value-added processing services do you provide?
    We provide comprehensive fabrication services including drilling, milling, cutting, welding, bending, assembling, and CNC machining. This allows us to deliver semi-finished or fully finished components ready for direct installation or assembly.
    How are the aluminum profiles packaged for shipment?
    Each profile is individually wrapped with a protective film to prevent surface scratches during transit. Profiles are then bundled together and wrapped with shrink plastic bags for secure outer packaging, ensuring they arrive in perfect condition regardless of shipping distance.
