It mainly provides precise shearing and customized cutting services for various types of hot-rolled, cold-rolled, galvanized and color-coated steel plates. The products are available in a wide range of specifications and meet the accuracy standards. They can meet the processing needs of multiple industries such as construction, mechanical manufacturing, sheet metal processing, home appliances, and auto parts. Our factory is equipped with advanced CNC shearing lines and longitudinal cutting equipment. We have standardized production workshops and professional technical teams. We strictly control the entire process from raw material inspection to precise processing and finished product delivery to ensure processing quality and delivery efficiency. Over the years, we have adhered to the concept of "excellent processing, honest service, efficient distribution", and have established long-term stable cooperation with many steel mills, traders and end customers. With excellent processing techniques, flexible customization services and complete logistics support, we have become a well-reputed steel plate processing and supporting service provider in the region.
Qingdao Sanhe Steel Co., Ltd. has a modern steel processing base covering an area of 80,000 square meters, specializing in services such as plate blanking, longitudinal shearing and cutting, and sheet cutting. Our main products include hot-rolled coil plates, cold-rolled coil plates, galvanized plates, and high-strength plates. These products are widely used in industries such as construction engineering, mechanical manufacturing, sheet metal processing, home appliance manufacturing, and automotive parts.
Our factory is equipped with a complete suite of advanced CNC processing machinery, including:
CNC leveling production lines — capable of processing steel thicknesses from 1.5mm to 25mm, ensuring flatness accuracy within 2mm/m for applications requiring strict flatness tolerances
Automatic slitting lines — for precision strip splitting across a wide range of widths, delivering clean edges and consistent dimensional accuracy
Hydraulic shearing machines — supporting custom-length cutting for both standard and non-standard size orders
We operate under a standardized quality management system that governs every stage of production — from incoming raw material inspection, through precision processing, to finished product verification before dispatch. Each batch is subject to dimensional checks, flatness testing, and surface quality inspection. Our quality control protocols are aligned with ISO 9001:2015 requirements, and our in-house testing capabilities are supported by our CNAS-accredited laboratory.
Our equipment and technical team support a wide range of customization services:
Cut-to-size cutting for non-standard lengths and widths
Precision slitting for coil strip processing
Leveling services for plates requiring enhanced flatness
With annual processing capacity exceeding 100,000 tons and substantial in-house raw material inventory, we maintain reliable production throughput and consistent delivery performance. Standard processing orders are typically completed within 7-15 days, while complex custom orders are scheduled based on processing requirements and confirmed with customers prior to production.
Our factory is staffed by a dedicated technical and operations team with extensive experience in steel processing. We maintain a scheduled preventive maintenance program for all equipment to ensure consistent production quality and minimize unplanned downtime. Our production management system tracks orders in real time, providing visibility into processing status and estimated completion timelines.
With over 16 years of processing expertise, we combine reliable equipment, skilled personnel, and rigorous quality control to deliver steel components that meet our customers' dimensional, material, and delivery requirements. We view our processing services as an extension of our customers' own production lines — reducing their secondary processing costs and material waste, while ensuring just-in-time delivery for their projects.
