To source door and window hardware from China, send a specification or sample to a manufacturer, approve a sample, confirm MOQ, finish and packing, then let the factory produce in about 20–25 working days and ship from Qingdao after a final inspection. HIPAD is a door, window, bathroom and stainless steel hardware manufacturer in Qingdao, founded in 2000, supplying rollers, hinges, handles, locks, window hardware and glass fittings to distributors, door and window factories and brands in 60+ countries. This guide explains each step, what to ask, and what to check.
A door hardware supplier can be a factory that makes the parts, a trading company that buys from several factories, or an agent who finds suppliers for a fee. Each has a place, but only a manufacturer controls molds, materials, production time and quality directly, and can change a design.

HIPAD started in 2000 with bearing assembly and precision rollers. That know-how grew into door and window hardware systems, and in 2020 into stainless steel handles, glass clamps, shower fittings and railing components. Today buyers can source rollers, hinges, handles, locks, window hardware and glass fittings from one factory, in matching finishes, in one shipment.
