Are you a manufacturer or a trading company?

✅ We are a professional direct manufacturer, not a trading company. Changzhou Guosu Technology Co., Ltd. specializes in high-end custom cold roll forming machines.

• Full in-house capabilities — we own our factory, design team, production workshop, processing equipment, and quality control system
• Complete process control — from profile analysis, machine design, processing, assembly, testing, to packaging and shipment

As a direct factory, we offer:

• Better control over production quality and delivery time
• More competitive and reasonable pricing
• Stronger custom design and technical support
• Faster after-sales response and solutions

We welcome customers to visit our factory for on-site inspection, factory acceptance tests (FAT), and business cooperation.
