Utility companies have the power to raise rates as they see fit, and the only way to fight back is by reducing your energy consumption. This is often easier said than done, but you should start by identifying areas where energy is wasted. If you feel a draft around exterior doors when they’re closed, you’re paying more than you should to maintain your desired indoor temperature, and the extra costs can really start adding up! But the good news is that weatherstripping can make a huge difference, and our team at National Custom Hollow Metal is ready to give you a same-day quote for two-part kerf frames!

When it comes to cancer, tumors, and other life-threatening illnesses, early detection is the key to ensuring the best possible clinical outcomes. Devices such as X-rays, CT Scans, and MRIs enable doctors and other diagnosticians to scan their patients without requiring them to go “under the knife,” and radiation therapy is an aggressive way to eradicate cancer in place of or in addition to chemotherapy. The health benefits outweigh the short-term risk of exposing patients to gamma radiation, but it’s crucial to protect the skilled technicians who operate the devices all day, every day!

Pocket doors are a time-honored option for subdividing larger office spaces or retail areas, and they also help make room in hallways or compact areas where conventional swinging doors would be awkward. Our team at National Custom Hollow Metal is proud to offer custom-built galvanneal and stainless steel pocket doors, and we’re standing by whenever you’re ready for a same-day quote!

Individuals who work in airports, factories, and on construction sites are accustomed to wearing hearing protection, but most of us are exposed to dangerous noise levels nearly everywhere we go! The typical city dweller or suburbanite is routinely exposed to noise levels of 50 to 70 decibels (dBA), and levels can reach 110 dBA near construction zones, airports, and highways. Excessive workplace noise has a detrimental effect on worker productivity and accuracy, and sustained exposure to 85 dBA or higher can cause permanent hearing loss.
