Protective gears ranging from harnesses to anchors to lanyards play a key role while working at height. Most of these gears are built to last for only a few years while others are designed specifically for permanent installation. One of the most commonly used protective worksite safety measures is to install a permanent freestanding guardrail as it provides edge protection on all the exposed edges of a roof.
Selecting the right type of guardrail is also vital. So how do you do that?
The answer to that is you will need to analyze the materials used to manufacture the guardrail, its design. You should also assess how long it will last.
This is one of the most critical factors to decide upon while purchasing guardrail. Consider that the guardrail will be exposed to other elements over the years and corrosion might take place over time. Check if the guardrail has a fine corrosion-resistant finish.
Products made of polyester-made rails or zinc-plated steel are acceptable for temporary use. However, you must look for stainless or galvanized steel if you want to exploit the benefits of the guardrails permanently.
In some cases, the decision may depend on the atmosphere and climate of the area. It has been found that zinc-plated steel increases in thickness to up to 0.001 square millimeters in extreme climate.
Permanent guardrails are designed in such a way that it can be attached to the roof before it is embedded by roofing and waterproofing. Unlike temporary guardrails which contain exposed latches for easy manual adjustment, permanent guardrails are adjusted with fasteners.
Designed in a unique fashion, it contains a counterbalance weight. Some permanent guardrails contain high-performance rubber mats which are placed in between the surface of the roof and base so that there is no adverse effect. The spreader plate of the guardrail provides more protection.
You might think that, ‘what if there is a hurricane or tornado or heavy windstorm? Won’t it knock down the guardrail?’
Well, the permanent freestanding guardrails can resist heavy wind loads and mild hurricane. But if there is a severe tornado, that would be really unfortunate. Nevertheless, a guardrail is capable of preventing fall as it is always designed under very strict rules and regulations.
It is always important to pay attention even to the smallest detail. Some people automatically assume that permanent guardrails will last a life time, but does is that true? Let’s find out!
Guardrails made of raw steel coated with powder can withstand harsh environment conditions where corrosion is a serious concern. The next best alternative is aluminum steel, which makes an outstanding guardrail because of its anti-oxidation properties.
Permanent freestanding guardrails are easily reversible to provide complete non-obstructive access. There are some guardrails which are designed specifically to provide a safe passage or an escape route in case of an emergency such as fire, earthquake, etc.
One of the best things about permanent guardrail is that it takes out the high cost out of the roof. The minimum number of components are used but it provides excessive protection. The freestanding guardrails do not need any kind of drilling. You do not have worry about special types of anchoring or any sort of penetration on the base of the roof. No kind of welding, threading or bending is needed while installing the guardrail.
Along with that, it doesn’t even require any special equipment for installation. How amazing does that sound? Permanent freestanding guardrails provide a wide range of safety applications and are almost adaptable to any kind of roofs.
