You must first know the desired height or length of your pier.

For example, if your height from ground to the underside of the bearer is say 750mm, then you would require a 600mm Uni-Pier post. You would then place the head on top of the post and adjust it upwards to reach your height of 750mm. The Uni-Pier head provides you with up to 200mm adjustment.

Uni-Pier posts are not sold by the metre length nor are they calculated on meterage scale. Uni-Pier post sizes start at 200mm and increase in height by 200mm ie 200mm, 400mm, 600mm etc

They continue in this manner all the way to 4000mm for Builders Grade 65 x 65mm and 5000mm for Heavy Grade 75 x 75mm.

The best place to know the price is to contact one our national stockists/resellers. Just email us using to enquire upon your nearest stockist/reseller.

Uni-Pier are Hot Dipped Galvanised to 600g/m2 which ensures that they provide maximum protection within extreme marine environments.

No other product can claim this and is the reason why Uni-Pier are so popular along the coast.

For added protection, within 2kms of crashing surf, we also recommend coating Uni-Pier with a 2 Part Epoxy.

In most cases, securing the head to the posts by means of screws is the most efficient way to do so. The screws are 14-20 x 22 Self Drilling, Self Tapping, Galvanised, Class 4 Metal Tek Screws.

We recommend a minimum of (6) six screws per post and head combination. (1) one screw can hold up to 800kgs therefore 4800kgs capacity can be realised.

The Uni-Pier system is fully engineered and designed to be secured in this manner.

However, bolts can be used as an alternative. These are M12 x 100mm Galvanised mild steel. We recommend (2) bolts per post and head combination.

Uni-Pier are perfect to restump houses. Often older houses will have engaged either brick, concrete, timber or even ungalvanized steel posts which all lend themselves to corrosion and a breakdown of the material.

Uni-Pier are hot dipped galvanised ensuring that your underfloor support does not corrode. The Uni-Pier system is quick and easy to install which makes it easier to replace corroded supports – especially under cramp areas under the house.

As a general rule of thumb, posts heights greater than 800mm and not surrounded by a masonry wall will require bracing.

However, this is a general rule only and, in some applications, bracing may still be required especially if a Structural Engineer has specified bracing into your project.
