They're basically putting together a heavy-duty handrail system for a wastewater plant we've been quoting, and teh corrosion specs on the HDG option are what sold it for us — the enviornment's brutal, so raw black wouldn't last a season.
The HM series uses precision-cast malleable iron, which gives you better thread integrity than most sand-cast fittings we've seen, and they're TUV and CE certified so inspectors won't flag it.
It's a no-weld, no-threading setup, so install crew can assemble everything with just a hex key on-site, which shaves about 30% off labor hours compared to welded pipe — we usually have stock for the 1-1/2" and 2" sizes, but confirm lead time for custom dimensoins.
The double coating option actually holds up better than HDG in salt spray tests, but it's about 15% more per unit and adds 20 days or so to production — most buyers go with HDG unless they're specifying for coastal exposure.
Also, we're not using these for anything that sees high-pressrue fluid flow; the clamp design is strictly for strucutral railing and guardrail loads, roughly 200-300 lbs per linear foot depending on the span.
Our standard MOQ is 500 pieces per size, but we can offer 50-100 pieces for sample testing. Just let us know what you need.
Yes, we can share TUV, CE, and ISO9001 certificates on request. They cover all surface treatments like HDG, powder-coat, and double coating.
For custom sizes with HDG, lead time is usually 25-35 days after order confirmation. Standard sizes are faster, around 15-20 days.
Absolutely. Our HDG option offers excellent corrosion resistance for harsh coastal environments. We recommend HDG for outdoor or marine applications to ensure long-term durability.
Yes, we support OEM packaging with your branding or barcode. Standard is carton boxes with pallets, and we can adjust to export-grade or bulk packing per your request.
