Guardrail Design and Custom Railings

If you are looking for a unique or custom railing, our team can design and install a wide range of railing designs. Each of our railing systems come with our patented flexible anchor systems. As long as you follow building code for railing, your custom guardrails can be designed and built with a wide range of options. Standard building codes require a 42″ high rail with an infill capable of rejecting a 6″ or 4″ sphere. Beyond that, the sky is the limit.

Our Patented Custom Railing Systems

Poma has developed a number of technologies for custom railings. Each of our systems control moisture, protect railings from spalling, and prevent corrosion. Protecting the base is important for railing systems designed for exterior spaces. It’s especially important for railings in coastal areas. Poma currently owns and maintains two patents designed to exterior railing.

Question & Answer: FAQ

Frequent Questions regarding Glass Railing systems

Q: Are glass railings as solid as older metal and picket railing systems? Can they withstand repeated impact from hurricane force winds?

A:  Yes, glass railing systems made by Poma are tested and have Miami-Dade product approvals. They undergo rigorous certification processes, including testing the assemblies to 2x the design load. This ensures an immense safety factor, making the glass railings just as solid and structurally safe as a masonry wall without the chance of concrete deterioration.

Q: How far from the balcony slab will the glass panels be, and how large will any of the gaps be between the new railing and the existing lateral structure?

A:  The glass railings will typically be situated approximately 6 inches on center from the slab edge. The gaps between the railing and the structure typically range from 1-1/2 inches to 3-1/2 inches, as the code requires rejecting any gap larger than 4 inches. It should be noted that railing set back may increase due to a variety of factors such as wind pressure, concrete compressive strength, existing rebar and rebar placement, balcony type and configuration etc. Final railing set back will be determined at the time of shop drawing development.
