1 Company Profile

Sichuan Steel Structure Intelligent Manufacturing Co., Ltd. is a controlling subsidiary of Sichuan Transportation Construction Group Co., Ltd. The company focuses on the fabrication and installation of various bridge steel structures, adhering to the principles of "intelligentization, digitization, standardization, lean management, and green low-carbon development." It aims to become a leading intelligent steel structure bridge manufacturing enterprise in Western China and a prominent player nationally.

2 Project Overview

The project is located within the factory of Sichuan Steel Structure Intelligent Manufacturing Co., Ltd., in the Ganmei Industrial Park South Zone, Meishan City, Sichuan Province. The procured advanced laser cutting equipment will be used for steel plate cutting and nesting in the combined workshop. The project also applies a material cutting production management system to enhance scheduling efficiency and accuracy, refine process control granularity, and promote the transformation of the cutting workshop into an intelligent cutting facility.

3 Construction Content

• Cutting Equipment

The cutting workshop includes preprocessing, plate storage, cutting, and finished part storage zones. Steel plates sequentially pass through these zones for respective processing. Nine 20kW laser cutting machines are installed in the cutting area as shown in the layout below, arranged across six bays. The equipment supports large-format plates (36m × 3.5m), bevel cutting, and marking/line-scribing functions. The laser source, head, operating system, bed, and working surface are all optimized with high-end configurations.
