TIANJIN METAL TOOLS CORPORATION manufactures professional non-sparking, explosion-proof hand tools with in-house national-level safety testing and advanced forging and machining capabilities.
TIANJIN METAL TOOLS CORPORATION is a China-based manufacturer specializing in professional non-sparking, explosion-proof safety tools. Reformed into Tianjin LongKing Hardware Tools Co., Ltd., the company supplies tools designed for work in combustible and explosive atmospheres where a single spark can create serious risk.
The product range includes tools manufactured from beryllium copper and aluminum bronze, offering key performance advantages such as non-magnetic properties, corrosion resistance, and strong tensile strength and hardness. These tools are widely used across oil and gas, petrochemical, chemical production, distilleries, paint manufacturing, gas pipeline construction, leather processing, electric power, defense applications, pharmaceuticals, shipbuilding, tankers, and aerospace-related environments.
Backed by heavy pressing equipment, numerically controlled machining centers, and over 100 specialized machines, the company maintains strict control over manufacturing, operations, and inspection. An in-house non-sparking safety testing center—authorized as the National Light-industry Quality Supervision and Inspection Center for Non-Sparking Tools—conducts impact, friction, and drop-hammer testing, applying Japanese standards alongside GB 10686-10693-89. Guided by the principle of “Safety First and Superior Quality,” the company focuses on stable quality, responsive service, and custom special-tool development to meet specific customer requirements.
