Cast Iron Collars/Studs
Cast iron collars and wrought iron collars are heavy-duty metal components designed for strength, durability, and versatile applications. While cast iron collars (molded for precision) and wrought iron collars (hand-forged for flexibility) share similar uses, they cater to distinct needs—from securing pipes to elevating architectural details. At Kubiao, we supply both bulk cast iron ornaments types to contractors, manufacturers, and DIYers seeking reliable metal accents.
Cast Iron Collars: High-compression strength (ASTM A48 Class 30) resists cracking under heavy loads—ideal for industrial machinery, pipe fittings, or heavy-duty construction.
Wrought Iron Collars: Malleable and corrosion-resistant (with hot-dip galvanizing or powder coating), perfect for outdoor use (fences, gates) or decorative projects.
Need a non-standard size? We offer:
Diameters: 20mm–150mm (adjustable for pipes, rods, or posts).
Finishes: Powder coating (200+ RAL colors), hot-dip galvanizing (rust-proof), or matte black (sleek industrial look).
Thickness: 2mm–8mm (tailored to load requirements).
Cut out middlemen—our collars cost 20–30% less than retail. Bulk orders (100+ units) get 15% off; 500+ units = 25% off. No hidden fees.
Industrial: Machinery guards, pipe couplings, conveyor belt rollers.
Construction: Securing heavy beams, anchor points for scaffolding.
Architectural: Fence posts, gate hinges, balcony railings.
Decorative: Garden edging, vintage furniture accents, vintage lamp bases.
