Innovative Material Handling

Mills, smelters and foundries have been proving grounds for our heavyweight Durowall belts, with the thousands of corrugated sidewall belts in use today as evidence they work hard and tough. Supported by experienced and skilled teams – including manufacturing, engineering, field services, product specialists and a nationwide salesforce – we work with customers to find the right solutions for their heavy-duty applications.

Popular heavyweight sidewall conveyor belt applications include:

Fabrication Options


Whether your corrugated sidewall project is new or existing, horizontal or vertical, Mi Conveyance Solutions will find the right combination of sidewall, cleats and belting needed for your application. We offer two types of sidewall belting: conventional and hot vulcanized.
  1. Conventional:
    • State-of-the-art hydraulic presses apply consistent and uniform pressure to ensure high adhesion levels between corrugated sidewall bases and belt covers
    • Automated precision buffing machines grind sidewalls and belt covers to maximize component bond strengths
    • Experienced technicians fabricate every belt to ISO standards

  2. Hot Bonded
    • Ideal for applications where a higher level of sidewall adhesion is required
      • High-temperature environments
      • Side-loading conveyors where material impacts sidewall first
      • Hard-to-access conveyors where elevated adhesion values serve as an economical insurance policy

Cross-Rigid Base Belting

Cross-rigid base belting helps deliver material in an efficient, cost-effective manner for applications that may challenge standard belts. That means a more efficient system without the worry of belt failure or downtime.
  • Eliminates belt bowing and cupping at the upturn and reduce sag on the return
  • Provides lateral stiffness while retaining longitudinal flexibility
  • Operates on standard pulleys without interfering with the conveyor structure

Sidewall Cleat Base Flexing DiagramOur Durowall belts were designed to allow for a variety of cleating styles to meet the needs of many applications. Cleats are bonded to the belt using hydraulic presses to ensure uniform pressure is applied during the bonding process. Taller cleats are bolted to the sidewalls to reinforce "pocket" strength. Cleat styles for heavyweight sidewall belts include:
