Imagine arriving at a wet Essex gateway after a long day to find a sagging, rattling gate that won’t latch while livestock mill about. If you hang or maintain heavy timber gates on a farm, smallholding or rural home, this guide is for you. In our experience, most problems come from wrong hinge sizing, weak posts or poor allowances for local ground and coastal conditions.
Read on to learn how to size strap hinges, choose hooks and hinge styles, set hinge centres and clearances, and pick latches that survive Essex weather. We also link to relevant products and installation guidance from Essex Concrete and Fencing so you can order the right kit with confidence.
Measure gate width, height and construction. A boarded or clad gate catches the wind and needs heavier gear than an open five‑bar gate. If you can’t weigh the gate, use supplier specs or compare with similar builds.
A common issue we see is undersized posts. For heavy gates use at least 175 x 175 mm timber posts with deep, drained footings. In Essex you must plan for clay movement and coastal salt—see our guide to fence post depth in Essex clay for footing details.
Aim for strap length of at least one‑third of the gate width; half‑width is safer on very heavy or clad leaves. Typical quick picks: 300–400 mm straps for 0.9–1.2 m gates, 450–600 mm for 1.8–3.6 m, and 600–762 mm for 3.6–4.2 m. When in doubt, go longer.
Match pin diameter to load: about 16 mm for light gates, 19 mm medium, 22–24 mm for heavy duty. In our experience, three hinges on wide or solid gates prevents sag—add the extra near the top rail. Always choose hot‑dip galvanised finishes for durability and browse our gate hinges to match sizes.

Hooks attach to posts in three common ways: face‑plate, through‑bolt (highest hold), or driven for a neat look. Adjustable band‑and‑hook sets save time at install and allow future tweaks—useful where posts settle.
Use cranked (offset) straps to make the gate sit flush to the post face; straight straps suit centre‑hung gates or where there’s clearance. Swap to stainless fittings in the most exposed coastal spots.
Transfer the hinge centres from the gate stile to the post accurately; mismatched centres cause binding. Typical positions are roughly 150–200 mm from the top and 250–300 mm from the bottom, moved to miss rails. Wider spacing increases stability.
Allow 10–20 mm between gate and post for seasonal movement and 50–100 mm ground clearance (75–100 mm on gravel). For anti‑lift security, fit the bottom pin pointing up and the top pin pointing down so the leaf cannot be lifted off the hooks.
For single gates a heavy‑duty galvanised ring latch gives reliable daily use. If you need to drive through frequently, choose an auto or spring catch. For pairs fit a throw‑over loop and at least one heavy drop bolt into a ground socket; two bolts are better on wide spans.
Keep fixings on the field side where practical to protect them from tampering and stock. Match the latch to use—see our gate latches for options with padlock eyes and durable finishes.
Hot‑dip galvanised parts outlast light zinc plate, especially near Tendring and the Thames Estuary where salt accelerates corrosion. Through‑bolt where possible using galvanised coach bolts and large washers; pre‑drill to avoid splits.
Do a simple annual check: oil pins and latches, re‑tighten fixings and touch up coating damage. Stock up on matching ironmongery so repairs use the same specification parts.

On timber use robust posts (min 175 x 175 mm for heavy gates) with drained footings and bracing for long runs. In clay, ensure the post base sheds water. On concrete or steel posts use bolt‑on hinge plates or through‑bolts—don’t drill slotted panel posts unless designed for it.
If you’re fitting on a steep drive, consider rise‑and‑fall hinges to lift the leaf clear as it opens. For mounting hardware options, see our fence post supports.
Mark hinge centres from the gate stile onto the post, drill and fit hooks square and level, hang the gate on the straps, use packers to set side and ground gaps, then adjust on adjustable sets to remove any sag. Finalise by oiling moving parts and tightening fixings.
People often under‑spec posts and hinge length—both cause early sag and noisy operation. In our experience, fitting a third hinge or going a size up on the strap fixes most early failures.
If you have a lightweight domestic garden gate or aluminium leaf, these heavy‑timber rules are overkill; use smaller straps, lighter pins and purpose‑made aluminium fittings instead.
Match hinge length and pin size to the gate width as noted above and favour adjustable band‑and‑hook sets for easier alignment. Pick a ring latch for regular access and an auto catch where speed matters. Finish with a ground socket for drop bolts and a gate stop to protect hinges.
Buying matching parts from one supplier reduces compatibility issues—find suitable gates, hinges and latches in the Essex Concrete and Fencing ranges linked throughout this guide.
Essex Concrete and Fencing supply locally tested hardware and timber that copes with clay movement, wind and salt. We fit and advise on this kit weekly, so if you need help choosing items to match your site, pop into the yard or call for practical guidance.
Choose adjustable if posts might move or you want easy future tweaks. Fixed straps are fine when posts are rock‑solid and set correctly.
Use stainless on seafront sites where salt spray frequently wets fittings; hot‑dip galvanised is sufficient for most inland Essex locations.
Yes—if the slope causes scraping as the gate opens. They add clearance but need correct alignment and slightly different hinge positions.
Check fixings and post movement, tighten or replace worn pins, and fit an adjustable hinge or third hinge to redistribute load. If the post has moved, repair or replace with deeper footings.
