What We Did on the Shop Floor

 Stopping Casting Defects 

When casting antique poles with dense floral patterns, the biggest risk is getting sand holes or swelling on the surface. If that happens, the post looks messy. For this batch, we used our resin sand casting line. Our mold engineers adjusted the iron pouring temperature to ensure the liquid iron filled every fine curve of the Victorian style. Every single post in this photo is clean, with no obvious casting flaws.

2-Layer Anti-Rust for Wet Weather 

Outdoor iron rusts fast if the paint is too thin. For this British green batch, we didn’t just spray paint. We put the raw iron posts through our automatic e-coating line first. This leaves a 15-20 micron base layer inside and outside the hollow tube. Then, we applied a 120-150 micron powder coating. This dual-layer specs mean the street lights won’t rust or peel even in rainy coastal regions.

Test Assembly & Seaworthy Packing 

These retro lights have heavy detachable brackets. To make sure the foreign distributor can assemble them easily without missing bolt holes, our QC team used custom gauges to test the fit 1:1 on the floor. After passing, the brackets were removed, wrapped in thick foam to avoid abrasion during the long sea voyage, and packed into heavy-duty plywood crates.
