Key Materials
Quality construction, built to last at sea.
- Bomar uses 535 magnesium hardened aluminum to construct our Commercial Grade Series inspection hatches. The raw almag-35 is heated to 1100 degrees F at the Bomar foundry and is then melted and poured into our proprietary cast molds.
- The Commercial Grade Series inspection hatches are professionally assembled in-house with 316L, marine grade, stainless steel T-handle & fasteners. Stainless steel is ideal for harsh marine environments due to it’s rust & corrosion resistance, strength and luster.
