H&B Supply Baltimore is the conveniently located Central Maryland Warehouse for H&B Engineered Products. In August 2016, we moved to a larger more convenient location in Linthicum, MD. This location has 10,500 square feet of storage, a dock and a ramp to assist with loading orders, and is easily accessible from I-95, I-895, MD-295, I-195, Rt. 1, and I-695. Our inventory includes diffusers, registers, grilles, spiral, and much more by some of the leading manufacturers in the HVAC industry including Titus, Donco, Eastern Sheet Metal, Loren Cook, MetalAire, and Elgen to name a few.
