Klockner Group

What Klockner Group does

Klockner Group LLC is a privately held industrial OEM based in Columbia, South Carolina, specializing in welded steel conveyor chains, precision-machined sprockets, and complete conveyor system solutions for heavy-industry applications. The company designs, fabricates, and installs engineered-class chain systems across the WH78 through WH158 series, custom drive assemblies, and wear liners, supported by proprietary heat treatment processes (including A-L asphalt chain rated to 800°F) and CNC machining capabilities. Its core technology stack combines mechanical engineering, proprietary metallurgy, and increasingly drone-based inspection tools (4K imagery and thermal imaging) for predictive maintenance services.

The company operates a diversified revenue model spanning hardware sales (welded chains, sprockets, drive units, wear liners), professional services (engineering, fabrication, installation, emergency repair), and inspection services (endoscope camera inspections, drone surveys). Pricing is primarily quote-based for custom engineered solutions, with unit pricing on standard chains (e.g., WH78 at $49.85/ft) and tiered volume discounts for bulk orders. Klockner serves multiple industrial verticals — pulp & paper, mining, asphalt, lumber, recycling, bio-energy, and steel manufacturing — through a direct sales model with nationwide field service crews and a warehouse network spanning Denver, Chicago, and Atlanta. The company has served the asphalt industry since 1958 (via its Kelco partnership since 1965) and has rebuilt over 80 cascade evaporators, positioning itself as an OEM with deep installed-base relationships and 24/7 emergency response capabilities.
