Sun exposure is not as much of a problem with our 3M sheeting built to last for up to 10 years. Our signs are weather resistant, so rain is not a problem for these signs. Made from aluminum metal material, these signs will not rust due to rain exposure. However, in the cases of severe weather that can damage a house and level a city, even we can't guarantee a signs survival. However, if you need to replace your signs due to storm damage, we are prepared and can provide those to you with fast delivery.
