Anvil® International Offers Labor and Cost Savings with New H-Block Rooftop Support Systems

Exeter, N.H., April 29, 2013 — Anvil International, the most complete manufacturer of domestic and globally sourced products for piping systems,has expanded its offering to include roof support systems with the addition of Haydon® H-Block Rooftop Support Systems.

"Anvil is committed to Building Connections That Last. The expansion of our pipe support offering is a strategic objective of ours." said Dean Taylor, vice president of sales & marketing. "Growing the breadth of our line will further Anvil’s ability to be a single source solution. We constantly look for ways to add value for our customer-partners."

Anvil’s offering of the new H-Block Supports are LEED Certifiable and UV-resistant and made in the USA from 100% recycled rubber. H-Block Supports offer higher load capacities, a lower environmental footprint, more durable material and better load factors. Pre-assembly and custom fabrication result in faster, neater and more efficient installation on any type of roofing surface. The improved longevity and performance in supporting pipe and tube on rooftops offers labor savings and cost savings over the product’s lifecycle.

"The biggest differentiators between H-Block Support Systems and other types of systems, such as wood blocking, are higher load capacity and more durable materials," said Jim Altzner, national hanger manager for Anvil. "H-Block Supports offer a specialized solution for the mechanical and piping industry, one that should offer real savings over the life of the system."

H-Block Supports are custom fabricated to specific applications, including solar racking, pipe and conduit supports, duct supports, HVAC supports, cable tray systems, air conditioning supports and roof walkway supports. The channels for H-Block Support assemblies also include a variety of options. The strut can be made in special lengths, finishes and alloys, including aluminum, stainless steel (both 304 & 316), PVC-coated, powder-coated, zinc trivalent chromium, pre-galvanized and hot-dipped galvanized.

The environmentally friendly H-Block Support Systems feature reflective orange safety stripes for maximum visibility and increased safety, alerting contractors to when piping is on the rooftop. Additional product benefits include:

  • 100% recycled rubber
  • LEED Certifiable
  • UV-resistant
