The different colors of wave beam guard rails can often be seen, with green being one of the standard colours. All these are due to powder coating or painting. What is the difference between these two processes? Here is a comparison by a wave beam guardrail manufacturer:
- Adhesion to the Surface:
- Powder-coated guardrails: Are smooth; scratches made by sharp objects on them will not be obvious. Powder coating has high adhesion.
- Painted guardrails: Have a rough surface and will scratch or chip even with minor rubbing. Paints have low adhesion.
- Durability:
- Powder-coated guardrails: The surface has a self-cleaning function because powder coating is electrostatic. The rain or water will make them clean easily.
- Painted guardrails: The rust spots can quickly occur by rain.
- Price:
- Powder-coated guardrails: Because of the costly production process, the market price for this product is higher than that of a painted guardrail.
- Painted guardrails: Because of the cheaper production process, the market price for this product is lower.
- Finish:
- Powder-coated guardrails: Are bright in color with a slightly glossy finish.
- Painted guardrails: Are somewhat less lustrous and therefore duller than powder-coated, and also tend to fade in color fast, which is quite easy to tell with a touch on the guardrails.
When intending to invest in wave beam guardrails one ought to be very conscious and do the study based on quality and the market price. Do not take a price that is far below the market average as a good deal. You get what you pay for, and you might not like what comes with choosing a cheaper option.
