Product Description
85# Series Casement Windows
Core Features
· Secure Integrated Grill Design
The fixed, multi-bar security grill is seamlessly integrated into the window frame, eliminating the need for external installations while providing robust protection against intruders. It maintains visibility and airflow without compromising safety, and our testing confirms it stays rigid even under 300N of force.
· High-Strength Aluminum Frame
Crafted from premium corrosion-resistant aluminum alloy, the sleek matte black frame delivers exceptional structural stability and durability. It passed a 16-hour salt spray test and maintains minimal deformation (0.03–0.06mm gap) under pressure, ensuring long-term performance.
· Double Glazing with Insect Screen
Features low-iron tempered double glazing for thermal insulation and noise reduction, paired with a fine mesh insect screen that keeps pests out without obstructing airflow. This combination enhances comfort while keeping your space protected.
· Smooth Casement Operation
Precision-engineered hinges and an ergonomic handle ensure effortless opening and closing. Our testing shows the operating force stays at just 61N (well under the 80N industry limit), with a steady 18N closing force and a reliable self-positioning force of 177–181N for secure placement.
· Modern Aesthetic
The sleek, matte black frame and minimalist grill design complement contemporary architectural styles, offering both security and visual appeal. The flawless, corrosion-resistant finish stays free of defects, preserving its clean look for years.
· Tested & Certified
Fully compliant with JG/T 127-2017 industry standards, and passed 35,000 cycles of repeated opening and closing without loosening or cracking. Every component is rigorously tested to ensure long-term reliability and peace of mind.
