Industrial Sectional Overhead Doors

The thickness is 40/50mm, which make the door panel has excellent mechanical properties,
the size is stable, even under low temperature the panels’ strength will not change; the panels’ long-term heat resistance temperatures are between -50°C-+100°C .
There are internal steel reinforce steel plate (1.0mm thick, and 16mm/40mm width) pre-laid along the panel at the joints, so the hinges could be fasten strongly on the panel to ensure the longtime service life. And also because of that the panel could be cut at any size to assembly doors with different sizes.
