TINNO Door is extremely painstaking in material selection. Its door frame is made of specially customized high-strength aluminum alloy material. This aluminum alloy is not an ordinary product but has undergone strict formula optimization. During the research and development process, engineers conducted a large number of experiments on low-temperature environments and precisely adjusted the proportion of various elements in the alloy to enhance the toughness and strength of the aluminum alloy at low temperatures.
Compared with ordinary aluminum alloys, the aluminum alloy selected for TINNO Door has a 30% increase in yield strength in a -30℃ environment, which means it can withstand greater external forces without deformation. Even in the extremely cold northern winters with howling winds and raging snowstorms, the frame of TINNO Door can firmly support and will not bend or break due to the material becoming brittle at low temperatures.
At the same time, the filling material of the door body is also crucial. TINNO Door selects a new type of polyurethane foam material. This material not only has excellent thermal insulation performance but also shows outstanding stability in low-temperature environments. The closed-cell rate of the polyurethane foam material is as high as over 95%. Under extreme cold condition.
3. Structural Optimization, Coping with Temperature Changes
TINNO Door has fully considered the factors of thermal expansion and contraction in the structural design and has carried out ingenious optimization. The door body adopts a unique elastic connection structure, and special elastic cushion pads are installed at the joints of various components of the door body.
When the temperature drops and the door body materials contract, the elastic cushion pads can automatically adapt to this change and provide a certain expansion and contraction space to avoid deformation caused by hard extrusion between components. When the temperature rises and the materials expand, the elastic cushion pads can also play a buffering role to prevent the door body from being damaged due to excessive expansion. This elastic connection structure has undergone tens of thousands of simulated temperature cycle tests and can ensure the normal use of the door body within the temperature change range from -30℃ to 30℃, without deformation or abnormal noise.
It is precisely by virtue of stringent material selection, innovative technology, and optimized structural design that TINNO Door has successfully cracked the problem of thermal expansion and contraction and can still maintain a perfect state in -30℃ extreme cold. For northern users, choosing TINNO Door means choosing peace of mind and reliability, allowing the home to remain warm as usual in the severe winter and fearless of the test of harsh weather.
