Window Reinforcements
Aluminum window reinforcements strengthen window frames, improve structural stability, resist wind and operational loads, and help prevent deflection, warping, and premature failure.
SHAPES WINDOW REINFORCEMENTS
Custom Aluminum Reinforcement Built to Your Specifications
SHAPES residential and commercial window reinforcements are custom designed to your exact profile specifications. Aluminum provides the strength and durability window and door manufacturers need, keeping frames secure and true to shape over years of use.
Crafted from high-quality aluminum, our reinforcements resist corrosion and wear for long-lasting performance. We work from your custom profile drawings to build reinforcement details that integrate seamlessly during insertion, so your manufacturing process runs smoothly from the first piece to the last.
Whether you need reinforcement for structural integrity or a specified DP (Design Pressure) rating, our lightweight yet sturdy aluminum components are engineered for easy install on the manufacturing floor.
