FACTORY WORKFLOW
Design & fabrication
Use drawings, manufacturing stages and delivery schedules to define custom components and interfaces.

PROJECT OVERVIEW
Henan Qingsong Membrane Structure Engineering Co., Ltd. is based on Miaowang Road, Xingyang, Zhengzhou, Henan and accepts drawing- and sample-based enquiries. The About page shows laser cutting, steel-beam welding, beam forming and powder-coating photographs, plus a 3D modelling example. This page explains how to check procurement needs around those stages; acceptance scope is project-specific.
About-page photographs show manufacturing activities and do not replace material or quality documents.
Confirm dimensions, connections and materials before production and promptly communicate site changes to detailing and fabrication teams.
Coordinate component numbers, finishes and packaging with installation order.
Component-only purchases, fabrication to supplied drawings and projects including installation require different information and responsibilities. State the arrangement when enquiring.
Reference photographs can start appearance and use discussions. They cannot replace the dimensions, connections and material documents needed for manufacture.
Laser cutting and forming depend on drawings and dimensions; welding and surface treatment need project-specific requirements and inspection records.
Factory photographs show actual processes but do not establish equipment limits, output or this project's acceptance results. Confirm procurement requirements individually in writing.
Plan component sections, numbers and packaging around transport, unloading and installation so deliveries can be checked easily.
Use consistent records for membrane fabrication and steel connections. Confirm changed site dimensions or new equipment before revising production.
INSIDE THE WORKSHOP


SCOPE & COORDINATION
