Company profile
From raw profile to finished place.
Jiangsu Haoyi Aluminum integrates independent R&D, production, installation and sales. Our range covers anti-collision barriers, bridge and landscape railings, riverway barriers, gates, fences, handrails, screens, pergolas and industrial aluminum profiles.
With automated machining and multiple welding capabilities, we work from the profile outward — matching section, finish, fabrication and installation to the demands of each project.
Engineered sections
Purpose-built profiles and component combinations.
Fabrication
Machining, welding and assembly under one roof.
Project delivery
Production through installation support.
Product systems
One material.
Many ways to build.
Explore systems by application, then open the technical series for profile codes, dimensions, weights and compatible components.

Representative data from catalog
Dimensions & weights may vary by specification
Custom work starts from your drawing, not from a standard catalog item. Send the application, profile requirement, finish expectation, quantity and delivery destination, and Haoyi will match profiles, connectors and fabrication details against the project requirement before production. A profile drawing alone does not establish the performance of a complete assembly; the required project standards should be identified before agreeing the supply scope.
How we deliver
Engineered as a system,
not a single profile.
A clear path from application brief to production and installation helps reduce mismatch between specification, fabrication and site.
01 / BRIEF
Define the application
Share drawings, dimensions, site conditions, finish expectations and target quantities.
02 / ENGINEERING
Select the system
Match profiles, connectors and fabrication details against the project requirement.
03 / PRODUCTION
Machine and finish
Produce, cut, machine, weld and assemble with controlled component compatibility.
04 / DELIVERY
Support the build
Coordinate delivery and installation support for complete aluminum systems.
From the catalog
Aluminum in place.
Real installations from the company catalog show how sections become barriers, entrances and outdoor rooms.

Questions before you enquire
What should I send for a custom solution?
The application, profile requirement, finish expectation, quantity and delivery destination, plus the profile drawing, system series and wall thickness if available.
Does a profile drawing alone prove the finished product will perform?
No. Performance must be assessed for the complete assembly and the applicable project requirements. Identify the required project standards before agreeing the supply scope.
What happens after I send a drawing?
Haoyi reviews the drawing and specification, clarifies the supply scope — profiles, processing, components and any assembly requirements — and then confirms the drawing and quotation details before commercial terms are agreed.
Can finishes and components be matched to a project?
Yes, within the project requirement. Share the finish expectation and component scope in the brief so they can be matched before production.
