Shed Threshold Protector - Protect Your Shed Doorway from Damp and Damage

The timber threshold at the entrance to your shed has a surprisingly hard life. Every time you walk through the doorway or wheel a lawnmower, wheelbarrow or other piece of garden equipment in and out, the timber receives another little knock. Add rainwater, muddy boots and the damp conditions of a typical British winter, and it's not surprising that shed thresholds can deteriorate.

Our shed threshold protector is a simple way to protect this vulnerable part of your shed. Made from folded galvanised steel with a black protective coating, it fits over the exposed edge of the timber threshold, helping to reduce wear, damage and moisture penetration.

Why Shed Thresholds Need Protection

The threshold is one of the most heavily used parts of a timber shed. Unlike the walls and roof, which are generally left undisturbed, the threshold is regularly walked on and subjected to impacts from equipment being moved through the doorway.

Lawnmower wheels, wheelbarrows and garden tools can gradually dent, chip and wear away the timber surface. Even small amounts of damage can break through the paint or timber treatment, leaving exposed wood more vulnerable to moisture.

Rainwater can add to the problem. Water carried in on boots or equipment, together with rain blown through an open doorway, can leave the threshold damp for extended periods.

Over time, repeated wetting and everyday wear can lead to timber deterioration and eventually rot.

Fitting a steel threshold protector provides a durable covering to the most exposed surfaces, helping to prevent this gradual damage before it becomes a more expensive repair.

A Simple Steel Protector for Your Shed Threshold

Our threshold protector is made from 0.7 mm galvanised steel, folded into an L-shaped angle measuring 50 mm across the horizontal face and 25 mm down the vertical face.

The exposed surface has a black, leather-effect plastisol coating. This gives the protector a neat appearance and provides an additional protective finish over the galvanised steel.

The horizontal leg covers the top of the threshold, where people walk and equipment passes over it. The vertical leg protects the exposed front edge, which is particularly vulnerable to knocks from lawnmower wheels and other garden equipment.

The protector is supplied in a 1 metre length, suitable for cutting down to fit many standard single-door shed openings.

It's a small, practical improvement that can help keep a sound timber threshold in good condition for longer.

How to Fit Your Shed Threshold Protector

Fitting the protector is a straightforward job using a few basic tools. You will need a tape measure, suitable metal-cutting tools, a drill with a 4 mm metal drill bit and a screwdriver or driver bit to suit the supplied screws.

1. Check the condition of the timber

Before fitting the protector, check that the existing threshold is sound and reasonably level. If the timber is rotten or badly damaged, it should be repaired or replaced first. The steel protector is intended to protect sound timber, not strengthen a deteriorating threshold.

2. Measure and cut to length

Measure the width of your shed doorway and mark the required length on the steel angle.

Cut the protector using suitable metal snips or a fine-toothed hacksaw. Carefully remove any burrs or sharp edges and protect the exposed cut edge against corrosion.

3. Mark the fixing holes

We recommend four fixing holes, each 4 mm in diameter, drilled through the horizontal 50 mm leg.

Position one hole approximately 50 mm from each end of the cut protector, with the remaining two holes spaced at approximately the one-third and two-thirds points along its length.

The holes should be positioned across the width of the horizontal leg to provide a secure fixing into the timber below.

4. Drill the holes

Using a suitable 4 mm metal drill bit, drill the four fixing holes at the marked positions. Remove any burrs from the holes before installation.

5. Position and secure the protector

Place the protector over the timber threshold with the coated face uppermost and the 25 mm vertical leg covering the exposed front edge.

Secure it using the four supplied black, exterior-coated pan-head screws.

The screw heads will sit slightly proud of the horizontal surface. As most shed doors open outwards, this should not interfere with the operation of the door. However, it is worth checking the clearance before fixing the protector permanently.

Once installed, the steel angle provides a tough covering to the exposed timber surfaces.

Will the Threshold Protector Fit My Shed?

The protector is designed for timber shed thresholds where a 50 mm horizontal covering and a 25 mm vertical return provide a suitable fit.

Because shed doorways vary considerably, it's worth checking a few dimensions before ordering.

Measure the width of your doorway to make sure the 1 metre length is sufficient. Also check that the angle will sit properly on the existing timber threshold and that the door has enough clearance to open and close freely.

The protector can be shortened to suit narrower openings, but it cannot be extended to cover a wider doorway.

It is suitable for protecting thresholds on new sheds as well as existing sheds where the timber is still sound but beginning to show signs of everyday wear.

Protect Your Shed Threshold Before It Deteriorates

Shed thresholds are easy to overlook until the timber becomes worn or starts to rot. Yet they are among the most vulnerable parts of a garden shed.

Fitting a galvanised steel threshold protector is a straightforward way to reduce the damage caused by repeated foot traffic, lawnmowers and other garden equipment, while also helping to protect the timber from surface moisture.

With its black protective finish, supplied exterior screws and simple cut-to-length installation, it's a practical improvement that can help extend the useful life of your shed doorway.

Order your 1 metre shed threshold protector and give your timber threshold a little extra protection.
