HULK Metal's sand casting foundry and investment casting plant have advanced production lines that can complete the production of handrails, guardrails, and glass railings quickly. For stainless steel glass railing fittings, we use the investment casting process to complete the orders and use the CNC machining center to complete the surface treatment, such as polishing, wire drawing, or titanium plating. For the handrails or guardrails of malleable steel and ductile iron, we will use the fully automatic sand casting process to complete the production. We have a quality control center to ensure that every batch of orders can meet your requirements.
