The EM 8/10 Combo portable seamless siding machines are the most user-friendly machines ever built. EXIM pioneered and patented the first portable embossing seamless siding machine. Today we are considered Number One in roll-forming technology and reliability, and have more machines in use worldwide than all others combined. Eastside’s siding machines feature our original self-contained embossing system, which applies a natural wood grain texture to paint finished steel or aluminum coil.
