Choosing the right fire-rated shim might seem like a small decision, but for engineers and architects, it’s a detail that can make or break a project. The right shim doesn’t just adjust hinges—it enhances fire-rated security, ensures proper alignment, and delivers peace of mind. But here’s the catch: not all shims are created equal. So, how do you find the one that’s built to meet your standards? Let’s break it down.
What is a Metal Door Shim?
A metal door shim is a thin, flat material placed between the hinge and the door or frame to correct alignment issues. It ensures smooth door operation, and consistent gaps, and prevents binding or uneven wear.
For professionals, metal door shims are often preferred because they provide durability, precision, and compliance with safety standards. In fire-rated and high-traffic commercial doors, this door hardware is highly recommended!
Types of Metal Door Shim
There are three common types of metal door shims: aluminum, stainless steel, and carbon steel. However, NFPA 80 (Section 6.4.3.4) mandates that only stainless steel shims can be used for fire-rated door assemblies. And here is why:
- Fire Resistance: 20, 45, 60, 90, or even 180 minutes.
- UL-certified for durability and safety.
- Aesthetically pleasing for professional installations, since stainless steel has been rustproof for years.
What to Consider Before Buying a Metal Door Shim?
Finding the right shim starts with asking the right questions, so ask yourself:
- Do you need fire-rated compliance? Not all shims meet NFPA 80 standards.
- What are the required dimensions? Does your project require specific lengths, widths, or thicknesses?
- Is ease of installation important? Look for adhesive-backed options to reduce installation errors.
- Will the shim be used for high-traffic or exterior doors? Ensure durability and resistance to wear and tear.
