The foam bottom creates a low-abrasion interface between the base and the roof surface, protecting the membrane from damage caused by point loading or surface movement. Hardware comes pre-installed in the base, reducing setup time on the job. The hot-dip galvanized steel construction and UV-stabilized finish make this base suitable for long-term outdoor exposure in direct sunlight and harsh weather conditions.\u003c\/p\u003e\n\u003cp\u003eThis post base is used in commercial and industrial rooftop installations where conduit racks, pipe supports, equipment frames, or solar panel array structures require a stable, non-penetrating mounting solution. It is compatible with a wide range of roof surface types, including single-ply membranes, bituminous surfaces, metal roofing, and spray foam roofing. The pyramid H-frame geometry distributes load evenly across varying rooftop surfaces, making it a practical choice for installations where surface uniformity is inconsistent. Electrical and mechanical contractors, as well as solar installers, commonly specify this base when rooftop penetrations are not permitted or practical.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFoam bottom provides low-abrasion interface for roof membrane protection\u003c\/li\u003e\n  \u003cli\u003eCompatible with single-ply, bituminous, metal, and spray foam roof surfaces\u003c\/li\u003e\n  \u003cli\u003ePyramid H-frame geometry distributes load evenly across uneven rooftop surfaces\u003c\/li\u003e\n  \u003cli\u003eMounting hardware pre-installed for faster field assembly\u003c\/li\u003e\n  \u003cli\u003eHot-dip galvanized construction for corrosion resistance in outdoor environments\u003c\/li\u003e\n  \u003cli\u003eUV-stabilized finish rated for long-term direct sun exposure\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use on rooftop surfaces including single-ply membranes, bituminous roofing, metal roofing, and spray foam roofing.

Before positioning the base, verify the roof membrane is clean and free of debris to ensure full contact with the foam bottom. No roof penetration is required, but consult local building codes and the roofing manufacturer's guidelines before placing any load-bearing hardware on the membrane. Confirm that the pre-installed mounting hardware is fully secured before attaching support framing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBase Type\u003c\/strong\u003e: Pyramid H-Frame Post Base\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBottom Material\u003c\/strong\u003e: Foam\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Hot-Dip Galvanized, UV Stabilized\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Roof Surfaces\u003c\/strong\u003e: Single-Ply, Bituminous, Metal, Spray Foam\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NVENT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: phb\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NVENT","offers":[{"title":"Default Title","offer_id":51267928391986,"sku":"PHB","price":158.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308910886.webp?v=1780694675","url":"https:\/\/voomisupply.com\/products\/nvent-phb-rooftop-h-frame-post-base-foam","provider":"Voomi Supply","version":"1.0","type":"link"}
