Kwaliteit en testen

As a reliable door and window hardware supplier with over 25 years of experience, HIPAD strictly controls every production step. Before shipment, all bulk orders of aluminum corner joints must pass rigorous quality inspections to ensure they meet international architectural standards and are ready for immediate assembly upon delivery.

Raw material inspection (Aluminum purity and strength)

Dimension accuracy check (Cavity fit testing)

Surface finish inspection (Smoothness and anti-corrosion check)

Assembly inspection (Seamless connection test)

Final quality control before packaging

Deze procedures zorgen voor stabiele productprestaties voor een langdurige samenwerking.

How to Choose the Right Corner Joint

To ensure optimal structural performance and seamless assembly, B2B buyers should confirm the following details before placing a bulk order:

Profile Compatibility: Ensure the bracket matches the exact cavity dimensions of your aluminum extrusions.

Installation Structure: Confirm whether your system requires crimping, screw-fixing, or adjustable corner joints.

Load-Bearing Requirement: Choose the appropriate material thickness and structural design based on the weight of the door or

window sash.

Customization Needs: Determine if specific surface treatments or custom dimensions are required for your regional market.

HIPAD can recommend suitable solutions based on your drawings, samples, or project requirements.
