Corflute or signflute is a versatile cost effective board that can be used for both internal and external locations. It is good for short to medium term outdoor uses, and you could use it for long term internal signage. It is quite light and rigid. Eyelets can be added if it is going to be attached to a fence for example using cable ties or rope. It is prone to folding so you do need to be a little careful with it.
It’s great for tradies fence signs, retailer sale signs, real estate signs and even wall signs. Keep in mind it does have visible ribs that run down one direction, which can detract from the look of the final piece.
