Q355 / SPA-H Weathering Steel

Certified atmospheric corrosion resistance 4-8x higher than carbon steel. Naturally forms a dense, self-healing oxide patina without painting.

Thickness Matrix (1.0 - 3.0mm)

1.0mm/1.5mm options for retail flat-pack series; heavy-duty 2.0mm/3.0mm plates for commercial tree pits and municipal parks.

Proprietary Rust Sealant

In-house developed patina sealer extends the golden-amber color stage and prevents powdery rust runoff from staining pavements.

Plant Safe & Soil Drainage

100% chemical-free organic planting safety, elevated drainage feet to prevent waterlogging, and optional internal thermal liners.

01 / Automated Production Line

Precision CNC Laser Cutting & Hydraulic Bending Workshop

Every corten steel planter panel is processed through high-power fiber laser cutting centers and multi-axis CNC press brakes. This guarantees seamless 90-degree corner joints, smooth deburred edges, and +/-0.5 mm dimensional repeatability across full container production runs.

  • High-power fiber laser cutting delivers clean weld-ready edges without slag.
  • CNC hydraulic bending ensures uniform angles and consistent corner seams.
  • Continuous TIG/MIG welding and internal corner gussets prevent soil load bulging.

Corten Steel Planter Wholesale Sourcing FAQ

Fast B2B clarity on steel grades, thickness options, MOQs, rust sealing, and plant safety.

What steel grades and sheet thicknesses are available for custom corten planters?
We fabricate from certified weathering alloy Q355 / SPA-H (equivalent to ASTM A588 / A242). Available sheet thicknesses include 1.0mm and 1.5mm for retail series, plus heavy-duty 2.0mm and 3.0mm for commercial landscape tree pits.
How does your proprietary rust sealant technology prevent pavement staining and lock color?
YardAve has developed a proprietary rust fixative sealant that stabilizes surface patina, extends the warm golden-amber color stage, and prevents powdery iron oxide runoff on light-colored pavers and indoor floors.
Does corten weathering steel harm plant health or soil quality?
No. Genuine Q355 / SPA-H steel is 100% non-toxic and organic safe. The iron oxide layer is chemical-free, and our planters feature elevated drainage bases with optional internal insulation to protect roots from summer heat.
What is the standard production MOQ for wholesale and custom corten planter boxes?
Standard production MOQ is 100 units per model/size. For mixed full container loads (20GP/40HQ) or commercial projects, we support mixed SKU orders starting from 50 units per specification.
How are large corten steel planters packaged for container export?
Planters ship either nested with protective foam spacers or knock-down (flat-pack) on fumigated wooden pallets, maximizing container cube utilization and preventing edge denting during ocean freight.
