Himmel Bros., Inc. was established in 1909 as a provider of custom aluminum extrusions and storefront glazing and entrance systems. In 1989, Leed Architectural Products Inc. acquired Himmel Bros., forming LHI Architectural Aluminum Products Division Industries, Inc.

Leed Architectural Products—or HA Leed, as it was known—was established in 1946 in Hamden, Connecticut, as a custom metals fabricator and manufacturer. Over the course of its growth, Leed Architectural expanded its product lines to include aluminum louvers, aluminum railing systems, column covers, custom wall panel systems, store front and entrance systems, custom curtain wall systems, interior aluminum fixtures, perforating, water-jet cutting and heavy plate aluminum fabrication.

The marriage of these two companies created a unique corporation with the ability to service a full range of architectural and industrial needs. LHI Architectural Aluminum Products Division manufactures and finishes a wide range of aluminum products for the commercial architectural industry, proudly offering one-stop responsibility. The extrusion division supplies all industries with custom aluminum extrusions.

LHI Architectural Aluminum Products Division has participated in some of the most prestigious buildings in the United States, with such diverse creations as control towers at airports, toll booths, custom facades, pressure-equalized rain screen systems, sun screens, curtain walls, decorative grills, and cut plate signage—to name just a few of our products!
