Stainless Steel Screw Jacks production

As the screw jack is very heavy especially for the one with a heavy load and long stroke, we value packing very much.

Every stainless steel screw jack is carefully packed with plastic wrap, foaming agent, and carton box before it goes into the export wooden case.

Fixed devices are built into the wooden box to prevent movement during transportation for the long stroke jacks, which ensures all parts are safe and sound after arrival.
