The Expansion Anchor Bolt for Elevator is a specialized fastening solution from Duojia Metal Products Co., Ltd., engineered specifically for secure elevator installations in high-rise buildings and industrial structures. Featuring a yellow zinc plated (YZP) finish on carbon steel for superior rust resistance, this bolt expands reliably in concrete substrates, ensuring stable anchoring for components like rails, motors, and cabins. Available in metric sizes M6 to M20 and grades from 4.8 to 12.9, it handles dynamic loads and vibrations inherent to elevator operations. Certified by ISO9001, ISO14001, ISO45001, and SGS, Duojia guarantees safety and quality from our Hebei factory. As a direct supplier, we offer minimum orders of 100 pieces, FOB prices starting at US $0.5, and free samples, with exports to markets like Russia, Britain, and Brazil. Ideal for heavy industry applications, this bolt provides vibration-resistant, corrosion-proof performance, making it essential for safe, efficient elevator setups worldwide.
Duojia’s Expansion Anchor Bolt for Elevator, with YZP coating, is produced in our advanced Yongnian District facility, drawing on over 25 years of expertise in high-strength fasteners. Made from galvanized or alloy steel, it features an expansion mechanism that activates upon nut tightening, creating a firm grip in solid bases like concrete. Our 5,000+ square meter plant uses tapping machines, forming equipment, and welding robots for precise manufacturing, supporting up to 500 tons monthly. Installation requires marking positions, drilling accurate holes, cleaning debris, inserting the bolt, positioning the elevator part, and tightening the nut to expand—avoid overtightening to prevent damage. Designed for rails and motors, it withstands operational stresses with regular maintenance checks. Backed by AAA certification including hardness and zinc tests, we provide custom options and after-sales with replacements within three weeks for defects. Exported globally, this bolt exemplifies Duojia’s focus on durable, eco-friendly solutions for elevator and infrastructure projects.
