Commercial Railing Solutions for Contractors & Architects

Choosing railing systems for commercial buildings

Every commercial project has different priorities. A hotel lobby needs clear views and a premium finish, while a school stair needs durability and easy maintenance. The table below compares the systems we supply most often to contractors and architects, so you can match each area of the building to the right commercial railing solution.

How to plan railings for a commercial project

Good planning saves money and prevents delays on site. These are the points our team reviews with contractors and architects on almost every commercial railing project.

1. Start with the code

In the United States, the International Building Code (IBC) sets the main rules. Commercial guards are generally required to be at least 42 inches (1,067 mm) high, and openings must not let a 4-inch (102 mm) sphere pass through. Guards also need to resist a 50 lb per linear foot load and a 200 lb concentrated load at the top. Handrails usually sit between 34 and 38 inches (864 to 965 mm). For public buildings, the ADA Standards for Accessible Design add handrail rules for ramps and stairs. Other countries have their own standards, so always confirm the code your project must follow. Our guides to deck railing codes and cable railing building code explain these rules in more detail.

2. Choose the right glass

Recent IBC editions tighten the rules on glass guards. As a result, laminated safety glass is now the normal choice for commercial glass railings, because it stays in place if a panel breaks. Tempered glass alone may still be allowed in some situations, but check with your engineer first.

3. Pick the right stainless steel grade

Material grade has a big effect on how a railing looks after five or ten years. We generally recommend AISI 304 for dry indoor areas, AISI 316 for outdoor, humid and coastal sites, and 2205 duplex for pools and very aggressive environments. Read more in our guide to why material grade matters for outdoor installations.

4. Plan budget and lead time early

Railings are often ordered late, which puts pressure on the schedule. Send us your drawings or bill of quantities early, and we will prepare an engineering budget by system and finish. That way, you can compare options before the tender and lock in the right solution.

5. Compare systems with the whole team

Architects, engineers and installers often have different priorities. Our contractor’s guide to glass, cable and post systems helps everyone compare cost, appearance and installation time in one place.
