The GH-PU518 industrial safety footwear is manufactured by Gaomi Guanghe Labor Protection Supplies Co., Ltd. (GUANGHE SAFETY) at our Intertek-audited 8,300 m² campus (Report #CNIR2607SH15266) in Gaomi, Shandong, China. Built to satisfy Metatarsal M Guard 100J, EN ISO 20345:2022, and ASTM F2413-18 standards, this protective footwear integrates premium upper materials with dual-density PU injection outsoles and breathable moisture-wicking interior linings across European and American size runs. Every production batch is destructively tested on our in-house Samsung Model 615 impact rig, confirming 200 Joules impact protection (residual toe clearance ≥ 14.0 mm), 15 kN static compression resistance, and ≥ 1,100 N midsole nail penetration resistance. Export shipments route via Qingdao Port (CNTAO) with flexible 100-pair private-label OEM MOQs and 15-day bulk turnaround, loading 3,200 pairs per 20GP and 7,200 to 9,200 pairs per 40HQ container.
GH-PU518 Metatarsal Guard Heavy Industry Impact Safety Boot
Equipped with an ergonomic flexible internal metatarsal shield that remains soft during walking but locks instantly upon impact, absorbing 100J of crushing energy across the upper bridge of the foot. Essential for metal stamping and casting.
