What Lumberock Premium Decking does

Lumberock Premium Decking is a composite-lumber manufacturer founded in 2000 and headquartered at 885 Church Road, Elgin, Illinois, operating as a brand under Engineered Plastics Systems, LLC and CMI Limited Co., which are portfolio companies of Capital Partners. The company designs, fabricates, and distributes marine-grade composite decking boards and complementary outdoor-living products (porch boards, railing systems, fencing) under four primary collections — Classic (residential rugged outdoor living), Coastal (marine-grade decking with a 24-inch span rating for waterfront applications), Veranda (historic-elegance styling), and Artisan (OEM/industrial/ manufacturing use) — and has recently added a fifth collection, Genesis, with two-tone finishes aimed at waterfront homes and family backyards.

Its core technology is proprietary composite-lumber formulation branded as XCR Technology, protected by an extensive patent estate spanning composition-of-matter, profile design, and method patents (US patents 7,025,539 through 11,021,845, plus design patent D871,899), and reinforced by registered trademarks (Lumberock, XCR Technology, BearBoard, Perennial Park Products). The product line is available in multiple board profiles (2x4, 2x6, 5/4x6, 2x8, 1x10, 2x2 baluster, piling strip, 4x4) in tongue-and-groove and groove-and-groove configurations for hidden fastening systems. Marine-grade durability, fade resistance, low maintenance (no staining or sealing), and a limited lifetime warranty are the principal functional claims, validated by ICC Evaluation Report ESR-2602 from the International Code Council.

Lumberock sells entirely through indirect channels: an independent-dealer and distributor network across the US, field sales representatives building customer bases in untapped US and international markets, contractor/builders, and an OEM/direct-sales motion for the Artisan Collection. Pricing is not publicly disclosed and customers must request a quote by phone (1-800-480-2327) or via the website, indicating a quote-driven, project-based sales cycle rather than transparent list pricing. Geographic reach spans the United States, the United Kingdom, and Europe, with industry-association memberships (US Green Building Council, Illinois Recycling Association, National Recreation and Park Association, Plastic Lumber Trade Association) supporting commercial specification.
