HTAN is one of the leading manufacturers of industrial hinges, handles and latches in China.
Once you have chosen a handle’s shape and size, there is still a quieter decision to make: how it fastens to the sheet metal. Through-hole and threaded-stud mounting both fix a handle…

The handle on an electrical cabinet door does two jobs that pull in different directions: it has to let an authorized technician open the door quickly, and it has to keep everyone…
Solar inverter cabinets, battery storage enclosures, and other outdoor equipment cabinets sit in some of the harshest conditions a hinge will ever face: full-day sun, wide day-to-night temperature swings, wind-driven rain, and…
