Vertical metal pickets outside a modern industrial building: how to space them to suit the façade

Look at the fence from the entrance and the car park as well. These are everyday views of the sheet-metal pickets, and a single design rendering may show neither of them. A trial section lets you examine the detail, while a drawing of the whole run shows how it fits the frontage.

Narrow pickets give the frontage a finer pattern. Wider ones draw more attention to each upright. Either width can work well if it suits the scale of the site. The depth of the ribs also matters because it affects how light and shadow fall across the metal.

Compare the finished profile widths. The width of the flat metal strip before forming tells you little about the pattern you will see. Stand several real pickets side by side to compare their colour, the shadows between the folds and the shape of the edges.

Fence posts divide the run into larger bays. Set them out in relation to the vehicle and pedestrian gates. They need not line up with every joint in the façade, but an unexpectedly short bay beside the main entrance can disrupt the appearance of the whole frontage.

Draw the pickets in each bay and count them. Keeping the clear gaps consistent may mean varying the end margins or using a different number of pickets. Resolve this before manufacture so the installer does not have to rip a picket lengthways to make the last one fit.

On a long frontage, check whether the uprights appear to bunch up near a corner. A small difference in bay width can work if it is spread deliberately over several bays. Avoid adjusting individual pickets on site without a setting-out plan. An elevation of the full run shows the proportions before you order and makes it clear which end margins are intended to differ.

Square-cut ends at a constant height produce a distinct top line. Rounded ends give a different outline and also need careful alignment. On sloping ground, consider stepping the bays or varying the picket lengths to suit the slope. Check that the chosen arrangement works with the frame and fixings.

Cut-to-length sheet-metal pickets make it easier to achieve the height shown on the drawing. The lengths on offer do not determine where the rails can go. Support each picket as specified for its profile and agree the top line and fixing arrangement together.

A dark fence stands out against a pale wall. Similar shades on the fence and façade can look quieter, although different gloss levels may still catch the eye. Compare coated samples outdoors, since a colour name alone tells you little about the sheen.

Metal pickets can also pick up the colour of window frames, door frames or flashings. This can bring the colours together without matching the entire wall. Look at these elements in one view so you can see how much area each colour occupies. Small swatches alone rarely convey that balance.

From inside the premises, the rails and fixings may be in plain sight even if the pickets have a decorative finish on both sides. Include their appearance and position in the design while keeping each support in the position required for the structure.

Build the trial bay with the actual fittings. You can then see the back of the fence and the junction at the post. The pickets already have their finished surface, but it takes a complete bay to judge the installed appearance and agree on the detail.

At the vehicle entrance, drivers may need clear sightlines. A service yard may benefit from more screening. You can vary the spacing while retaining the same profile and colour. Set out each change in advance and check that the supporting structure suits the arrangement.

A small gap alone does not guarantee privacy. The viewing angle and distance from the fence also matter. An open fence must still meet the site’s security needs. Establish what the fence is meant to do in each part of the grounds.

Use the first completed bay to check the spacing against the design. View it beside the building from the usual approach distance and at an angle. Vertical metal pickets can give a long frontage a consistent appearance when their proportions suit the building. Repeat the layout once you are satisfied with the spacing in place.
