Dowd Adjustable Deck Supports for Sturdy and Level Decks

 When building a deck, it's essential to understand the requirements for deck supports. In this comprehensive guide, we'll cover important aspects such as determining the number of supports needed, selecting the right timber, and the advantages of Dowd Adjustable Deck Supports. We'll also provide insights into installation and height adjustment for a sturdy and level deck structure.

How many deck supports do I need for my deck/ What are the spacings?

The number of deck supports required depends on the size and span of the timber being used. Thicker timber allows for wider spacing between supports. It is generally recommended to use 140 x 45mm or thicker timber for a sturdy deck. Consult local span tables and building codes to determine the specific requirements for your area. If unsure, it's advisable to consult with a structural engineer for expert guidance.

We found this guide to be helpful here, but refer to an engineer if you are unsure.

Timber Selection for Deck Supports

Treated structural pine is commonly used for deck frames due to its durability and resistance to decay. The choice of treatment grade depends on the exposure and specific conditions. Here's a quick overview of treatment grades and their typical uses:

Treatment Grade	Exposure	Specific Conditions	Typical Uses
H1	Inside, above ground	Completely protected from the weather and well ventilated and protected from termites	interior joinery
H2	Inside, above ground	Protected from wetting	Framing, flooring and other similar uses in dry conditions
H3	Outside, above ground	Subject to periodic moderate wetting	Weatherboard, facia, bargeboards, window joinery and decking
H4	Outside, in-ground contact	Subject to severe wetting and leaching	Low level decking, Fence posts, pergola posts (in-ground), landscaping timbers and retaining walls
H5	Outside, in-ground contact	Subject to extreme wetting and leaching where you require a higher degree of protection	Retaining walls, piling and house stumps
H6	Marine Water	Subject to prolonged immersion in sea water	Boat hulls, marines piles, jetty cross bracing
