The main structural materials of European-style pure wood and high-end aluminum-clad wood series doors and windows are made of high-quality larch or red pine grown in the original forests of Russia. The characteristics of broken bridge aluminum and its growth environment determine its unique advantages as a door and window material：The resin channel is small, the paint performance is good, and it is water-resistant and corrosion-resistant;The wood is dense, with moderate hardness, strong wood grain texture, and straight grain. Cut materials are cut to ensure texture and strength. For cross-cut boards, the width of the finger surface and the angle of the growth rings are nearly 90 degrees, and the wood texture presents a straight line throughout the body. In this way, the wood with broken bridge aluminum along the grain has high compressive and bending strength, small dry shrinkage and wet expansion, and is not easy to warp and crack. Cross-cut laminated lumber unifies stable product performance with beautiful appearance, and also largely avoids the impact of various defects in the wood itself on product quality.
The logs collected from Broken Bridge Aluminum are dried in a cycle steam drying kiln, joined and other processes to make laminated timber. The moisture content of wood is maintained at8%-12% to ensure the stability of its performance. Three layers of radially cut plates are selected and finger-jointed laminated lumber is used, which is glued with AKZO NOBEL glue. The thickness is bonded in three layers and the length is finger-jointed. Carefully selected high-quality larch laminated lumber has stable performance and clear texture, ensuring excellent product quality to the greatest extent, and perfectly combining the practicality of doors and windows with artistic aesthetic appeal. The hardware is imported from famous European manufacturers, such as German Noto, Silkia, etc.
1. Hardware material: broken bridge aluminum. Various rods and some small parts are made of high-quality cold-rolled strip steel and section steel. Made of refined zinc: lock blocks, hinges and other small parts are made of high-quality refined zinc alloy through die-casting process
2. Surface treatment method of hardware: The surface of the hardware is galvanized, chromated and impregnated. The anti-corrosion performance complies with the requirements of German RAL-RG R607/3 for casement-opening bottom-hung hardware. stipulated quality standards. The basic colors on the surface of the hardware are traditional yellow and silver, which represents technological development trends and aesthetic fashion trends.
