  • Can be removed (backed out) if necessary
  • Screws are available to suit softwood or hardwoods
  • No pre-drilling or countersinking required in most cases
  • Screws can form part of the aesthetic appeal of the deck – stainless steel screws are not only highly resistant to corrosion but can also be visually appealing.

Which screws should I use for treated pine decking?

Otter Chemshield Treated Pine Decking screws are the perfect choice for most environments. They feature small heads for minimum visual impact and do not require pre-drilling or countersinking when fixing into softwoods. The Chemshield coating is designed to withstand the corrosive properties of chemical timber treatments and will outlast galvanizing.

In extreme environmental conditions (e.g. within 1 km from the sea, pool / spa surrounds) always use Otter 316 grade stainless steel decking screws.

Which screws should I use for hardwood decking?

Otter Self Drilling & Embedding Hardwood decking screws are specially designed for all types of hardwood decking timbers including spotted gum. They have a patented drill point and aggressive nibs under the head and do not require pre-drilling or countersinking. Available in Brown Chemshield finish to blend with the timber colour or stainless steel for harsh environmental conditions

How many screws or nails should I use to fix the decking?

Two fasteners should be used at each intersection of the decking timber and joist.

Why use balustrade?

Balustrade on the deck perimeter can act as a decorative boundary or safety barrier to prevent furniture or persons accidentally falling off. Be aware, even a small change of level can be a hazard for toddlers and the elderly.

Can I install balustrade myself?

Otter has a DIY friendly 316 grade stainless steel wire and bullet balustrade system that is easy to install and looks ‘fantastic’. No special tools or skills are required to achieve a modern professional look.

How long would it take me to install the Otter Balustrade system?

It would take less than half a day for an average deck of 3.0 x 4.0 metres.

What's the difference between hardwood and softwood?

Hardwood and softwood are general terms used to describe species of wood. The terms have nothing to do with the physical hardness of the wood. Hardwoods come from broad-leaved trees and softwood species from coniferous, evergreen trees. Softwood decking timbers are chemically treated to prevent rot, mould and fungal decay. Always use Chemshield finish screws in ACQ treated timbers.

Do I need planning permission to build a deck?

Timber decks differ from conventional patios and terraces most significantly in their elevation and general height of construction. Property owners should satisfy themselves that planning regulations do not apply to their proposed structure. Council approval may be required along with a full set of plans and certification.
