Hello everyone, when purchasing lifting chains, you might wonder how to ensure you're buying genuine stainless steel chains? What if the tensile strength doesn't meet Grade A? Could some manufacturers pass off inferior products? How should you identify them? Dateng Chain Machinery Manufacturing Co., Ltd. is here to ease your concerns. We include a tensile test report certificate with each shipment, making the strength clear at a glance—so you can buy with confidence and use with peace of mind.

-: Introduction to the broad categorization of lifting chains, focusing on key classifications!

(1) By use: Lifting chains can be divided into high-strength chains, binding chains for chain hoists, and special lifting chains.

(2) By material: Lifting chains can be made from 201, 304, 316, 316L, 310.

(3) By specification: 1.5mm anti-drop chain, 2mm tag chain, 3mm clothes drying chain, 4mm miner's lamp chain, 5mm protective chain, 6mm lock chain, 6.5mm fence chain, 7mm manual hoist chain, 8mm marine chain, 9mm lifting bar, 10mm lifting chain, 12mm lifting chain, 13mm lifting chain, 14mm lifting chain, 16mm lifting chain, 18mm lifting chain, 20mm lifting bar, 22mm lifting bar, 24mm lifting bar, 26mm lifting chain, etc. Custom specifications are available.

Grade A lifting chains are a type of high-strength, high-temperature resistant, and wear-resistant lifting chain. High-strength lifting chains are made from high-strength steel, and Grade A lifting chains are also made from high-strength stainless steel, so Grade A is a subset of high-strength lifting chains. The surface of lifting chains can be polished, blackened, painted, plastic-coated, or electroplated to adapt to harsh environments with high humidity, acidity, or alkalinity.

Our company uses a full automated process including chain weaving, output, calibration, heat treatment, tensile testing, finishing, and final inspection to ensure a 100% pass rate for all lifting chains. The high-quality products provided by our lifting chain manufacturer are widely used in factories, workshops, mines, marine cranes, and more due to their reliability and superior quality. We adhere to the principle of high quality and low prices, professionally providing customers with excellent products. We believe that high-quality Grade A lifting chains offer customers more safety and less risk.
