Slide With a tradition of engineering excellence and proud craftsmanship that stretches back to 1866, Merchant & Evans, Co. offers an advanced line of quality metal cladding systems and component accessories. Let's take a quick look into their rich history... Slide In 1866, Lieutenant Commander Clark Merchant started Merchant & Company, Inc. and ran it until his death in 1902 when his partner and engineer Powell Evans took his place. Over the next several years they produced tin plate and sheet metal specialty products out of various locations across the country under the new name of Merchant & Evans Company, Inc. Slide M&E, Co. quickly established itself as an early leader in tin and sheet metal manufacturing. In 1964, the ZIP-RIB structural panel was introduced. Many of the early ZIP-RIB roofs are still in tact today and it remains one of the most stringently tested panels on the market. Slide M&E, Co. maintained their tradition of engineering excellence & craftsmanship through the new millennium. M&E, Co. joins Garland Industries and IMETCO in 2020. This continued success led to high profile projects like Apple Park

We are excited to continue making history with

The ZIP-RIB structural metal roof panel system is designed for roofing on slopes 1/4” per foot or greater and can also be used as a vertical wall panel. Its mechanically seamed ribs are 2-1/2” high and panels are available in widths of 12”, 16” or 18” (nominal coverage). Wider widths up to 22” are subject to inquiry. Specialty manufacturing options such as conical tapers, convex and concave curves and continuous lengths exceeding 460 feet are available with this time tested system. ZIP-RIB can be applied over open purlins, re-roof framing, plywood or metal deck.
