Our Aluminum Non-penetrating Guardrails provide a portable or permanent fall protection system for leading edges. The guardrail systems are customizable for added versatility and provide passive fall protection for the user, incorporating the durability and reliability needed to get the job done and are aesthetically pleasing for any building type.

The Aluminum Non-penetrating Guardrails act as rooftop railings and are non-penetrating to prevent roof leakage. The guardrail roof railing solutions are designed to be easily assembled on the roof surface without penetrating the roof membrane. Systems can be designed for any roof or building structure per OSHA requirements.

Comprising straight, curved or inclined aluminium uprights, with top and knee rails, all connected via a clamping system to allow fast assembly and accurate level adjustment. No requirement for drilling, the system is mounted directly on the platform.

Complies with requirements of EN 13374 and EN ISO 14122-3, section 8.2, and conforms to European Directive 2001/45/CE.

Finish: Brushed Aluminum, Weather Resistant

Fall Protection Challenge

When you need a fall protection system to protect roof leading edges and openings a fixed guardrail system may not be an option. Fixed systems require roof penetrations that are expensive to waterproof and do increase the possibility of future roof leaks.

Fall Protection Solution

A non-penetrating aluminum guardrail system will allow you to implement a passive fall protection system without roof penetrations. In addition the system can be cut and fitted onsite without the use of special tools for a custom finish.

Aluminum Modular Guardrails - Straight Upright Aluminum Modular Guardrails - Curved Upright Aluminum Modular Guardrails - Folding Upright
Straight Upright
A simple but traditional design which fits in perfectly with the clean lines and angles of a building. The straight upright system is particularly suitable for protection at access points and demarcation of walkways.
Curved Upright
The curved upright system reinforces the design of a building and is an aesthetic addition to a structure. This solution also keeps people further from the roof edge, giving a greater level of safety.
Folding Upright
The folding upright folds away or collapses. The appearance of your building is minimized and your guardrail is visible only when it is needed.
(Additional fall protection is advised, in form of single anchor points for example, to safely fold out the guardrail system when it’s needed)

If you are trying to decide between a Horizontal Lifeline System on your roof versus a Non-penetrating Guardrail System, consider the following:

Non-penetrating Guardrails
Aluminum Non-penetrating Guardrails
Horizontal Lifeline & Anchors
CAI Safety Roof Horizontal Lifeline Anchor
Engineering must verify that your building structure can support the fall arrest loads. NOT REQUIRED REQUIRED
Roof penetration and sealing to accommodate anchors. NOT REQUIRED REQUIRED
Installation by a certified installer of horizontal lifelines. NOT REQUIRED REQUIRED
Training all employees who use the horizontal lifeline system. NOT REQUIRED REQUIRED
Annual inspections required on all fall arrest systems (semi-annual if in California). NOT REQUIRED REQUIRED

Non-penetrating guardrail systems have many advantages over horizontal lifelines. There are exceptions and we will be glad to discuss them with you.
