With Horizon-Loc (H-Loc®) you can enjoy a stunning metal roof or siding with no exposed fasteners (which means no screws show on the panels!). This gives you all the advantages of a standing seam roof at a lower cost. The panels snap together, making installation quick and easy, without the need for mechanical seaming. As a result, you can save money on labor costs compared to traditional standing seam panels.

Horizon-Loc is ideal for residential roofing or siding and light commercial applications applied over solid decking, and its durability ratings may lower insurance rates to save you money. Extra protection from leaks, no hand-seaming, and lower insurance rates make Horizon-Loc the perfect panel for a wide variety of projects.

  • Installs over solid decking with 30lb. felt paper or equivalent.
  • Available in painted AZ50 Galvalume or AZ55 acrylic coated Galvalume.
  • Matching trims and accessories in both hidden or exposed fastener style.
  • Comes in over 20 colors with several in a textured matte finish.

Our metal offerings are fire-resistant, termite-proof, and available in a variety of styles. In addition to this, we also offer CentralGuard to protect your project and investment whether it is for a metal roof or exterior cladding.

Horizon-Loc comes in a multitude of popular colors to complement your project and other finish materials. Contact your sales representative for custom color options.
