MDO Boards for General Contractors, Commercial Real Estate Firms, and Construction Companies

MDO – or Medium Density Overlay plywood – is one of our most popular outdoor sign materials. Made up of 1/2 inch finished plywood, MDO boards are either primed or enamel painted on either one or both sides and are durable enough to last for years outside. Available in 4’x8’ or 4’x10’ panels, MDO can either be cut to smaller sizes, or combined together to make sign faces 16’x32’ and larger. Their sturdiness makes them the default choice for free-standing post-mounted installations. Most commonly used for General Contractor signs, Commercial Real Estate signs, and Construction company signs.

In short, we’re experts at it!  Signs of SA has installed literally hundreds of these signs over the years; for all kinds of customers, for all kinds of needs.  There are all kinds of sizes and configurations and installation methods to choose from.  From small 2’x4’ signs, to gigantic 16×32’ site boards.  We can work with you from setting up your artwork, to advising sign size to installation type and set-up.

True to our reputation, we are also one of the lowest cost MDO sign providers around.  But we do not skimp on materials – we use quality, treated primed or painted boards designed to withstand the elements for years.  We still see MDO signs we did over 10 years ago in the field!

Couple with our UV and graffiti-resistant overlaminate, our signs remain vibrant and resistant to fade for years and years.  And should your sign get tagged, as long as it had our laminate, graffiti just wipes off!

We know your time matters – and we value that.  We are one of the fastest sign companies around.  Where some sign companies take 2-3 weeks to complete a sign, our MDO signs are usually completed within a couple days.
