Aluminum Fence Manufacturers : How to Pick a Real Factory
Home  >   News & Blogs  >   Manufacturer information

When you search for “aluminum fence manufacturers”, you're looking for more than a “seller”—you need a real factory that can control production quality, handle custom orders, and deliver on time. But 40% of “manufacturers” online are actually traders: they don't have their own workshops, so they can't fix quality issues or speed up production.

 

A reliable aluminum fence manufacturer owns production lines, has a professional R&D team, and can show you every step of making your fence. In this guide, we'll share 4 ways to tell “real factories” from “fake manufacturers”, and explain why Shimei (实美) — with 15 years of manufacturing experience — is trusted by 12,000+ global clients. We'll also highlight our full product line (fences, railings, gates, windows/doors) for one-stop sourcing.

 

1. 4 Ways to Spot a Real Aluminum Fence Manufacturer (Avoid Traders)

Not every “aluminum fence manufacturer” has real production capabilities. Here's how to verify:

1.1 They Own a Physical Factory (With Production Lines)

Traders only have offices—real manufacturers have workshops with:

●Extrusion lines (to make aluminum profiles, not just buy ready-made ones).

●Powder coating booths (to control color consistency and adhesion).

●Assembly lines (to ensure fence panels fit perfectly).

 

Ask for live factory tours (via video call) or recent production photos (with timestamps). Traders will hesitate or send stock images—real factories will show you their lines in action.

 

Shimei has a 700,000㎡ factory in Guangdong and Hubei, China with 20 extrusion lines, 4 powder coating booths, and 6 assembly lines. We offer daily live tours: you can watch workers extrude aluminum profiles, test coating adhesion, and assemble fence panels in real time. No tricks—just real manufacturing.

 

1.2 They Have In-House R&D & Customization Capabilities

Traders can only sell standard models—real aluminum fence manufacturers can modify designs, materials, or processes to meet your needs. For example:

 

●Adjusting aluminum wall thickness for high-wind areas (e.g., 3mm vs. 2mm for coastal projects).

●Developing custom powder coatings (e.g., anti-graffiti for commercial fences).

 

Shimei's R&D team (15 engineers) creates 50+ new designs yearly and handles 500+ custom requests annually. For a Canadian client, we developed a “cold-resistant fence” (using modified 6063-T5 alloy) that withstands -50°C—something traders couldn't do. We also make matching railings, gates, and windows/doors for custom projects (one-stop sourcing saves you time).

 

1.3 They Control Quality at Every Production Step

Traders can’t check quality—they just resell products. Real manufacturers have strict QC at 4 key stages:
