Material Integrity
We utilize 100% primary aluminum as our raw material for profiles. The frame profiles are manufactured from 6063-T5 / 6063-T6 aluminum alloy, while the door panels are fabricated using 6061-T6 or 5052-H32 aluminum sheets.This material selection represents the most standardized, mature, and reliable solution widely adopted in the aluminum door industry.Learn More

Surface Science
Acid Washing Process
Employs chemical pickling to thoroughly remove residual impurities and activate the surface, providing a highly clean substrate for painting and improving coating stability.
Salt Spray Test
Simulates high-salt corrosive environments to evaluate coating corrosion resistance, adhesion, and integrity, serving as a key test for verifying the long-term protective performance of outdoor aluminum products.
Acoustic & Airtightness
Our main doors feature a double-layer rubber seal design, using EPDM rubber strips (the same material as automotive weatherstripping). They deliver exceptional sound insulation performance. When properly installed, the sound insulation difference between the interior and exterior can reach 80 to 90 decibels or more.Learn More

Security Architecture
We provide customized structural systems for our entrance gates to suit diverse application scenarios, such as non-thermal break structure, thermal break structure, and off-axis structure. The internal core of the gate is constructed with an aluminum alloy framework, filled with either aluminum honeycomb or high-density flame-retardant polyurethane.Learn More
