Installation tips
For a 175 cm high gate, allow 4 cross rails per leaf (every 40–45 cm) and a diagonal brace to counterbalance the weight and prevent warping. Pre-drill each board before screwing – timber stresses are greater at 175 cm than at 120 cm. Treat every surface and end-grain face before assembly. Use stainless-steel screws of at least 4x50 mm to fix the boards to the cross rails.
Spacing between boards: a solid gate acts like a sail in the wind, placing considerable strain on the hinges and posts. A gap of 15 to 20 mm between boards significantly reduces these forces and is recommended for wide gates and windy areas. A 10 mm gap gives an almost fully screened appearance. Beyond 25 mm, the slatted effect lets light through and allows people to see through the gate.
Care and protection
Reapply exterior wood stain or oil every 2 to 3 years. Inspect the bottom ends annually – the lowest 15 cm of the boards retain the most moisture. Douglas fir greys naturally without treatment but remains structurally stable for several years.
WoodUp tip
Before you buy: this 175 cm board is sized for tall gates and some high fences. Check the exact height of your project before ordering. Compatible with WoodUp 91x21 mm cross rails. Untreated fir and Douglas fir need exterior treatment before installation, paying particular attention to cut ends if you adjust the length.
Frequently asked questions
Can this board be cut shorter for a gate under 175 cm high?
Yes. Solid wood can easily be cut with a circular saw. Treat the exposed end grain immediately after cutting to protect the fresh cut.
How many boards are needed for a gate 3 m wide and 175 cm high?
With 91x21 mm boards fitted edge to edge, allow around 16 to 17 boards for each 1.5 m gate leaf, or 32 to 34 boards for both leaves. With 15–20 mm gaps, allow around 13 to 14 boards per leaf.
Are WoodUp gate kits available at a height of 175 cm?
No. WoodUp gate kits are available at a height of 120 cm. For a 175 cm gate, you will need to build it yourself using these boards, cross rails and a diagonal brace.
What post section is needed for a 175 cm gate?
For a 175 cm high gate leaf, allow for posts of at least 120x120 mm set 80 cm into the ground, or set metal posts for the best resistance to wind and weight.
Is untreated Douglas fir suitable at this length?
Yes. Douglas fir is the recommended wood species for tall gates because its natural class 3 durability allows it to last several years without treatment. Fir must be treated initially to prevent rapid deterioration.
