The colour of a fence picket is only the most visible part of the material. Beneath it lie the steel and the surface protection system. Each layer has its own job. Metal pickets that look alike therefore do not have to share identical parameters. The choice is best based on a specific material description rather than on the shade alone. The rear face and the conditions in which the fence will be used also matter. The coating is a protection system, not just decoration. Sheet-metal pickets are made from thin material profiled to a specific shape. The steel grade and thickness work together with the geometry of the cross-section. These determine how the element behaves once fixed. A coloured surface does not replace suitable material or proper supports. Rigidity should therefore not be judged by the name of the coating alone.

Metal pales are worth considering when you want a repeatable appearance and less maintenance work, but not full privacy. Before ordering, check how the system handles corners, the gate and the side gate, as these determine the even rhythm of the bays. Filling density is another key variable: a denser layout gives more privacy but increases wind load, so leave the choice of posts and foundations to the designer. Assess both sides of the element and access to a single pale.

On pickets you can see narrow grooves, wider pressings and larger smooth areas. These details affect the appearance and the geometry of the element. However, they do not create a simple quality ranking. More lines on the surface do not automatically mean a better product. Metal pickets must be assessed as a complete cross-section, together with thickness and support. The term “micro-profiling” is sometimes used descriptively, so it is worth checking the actual drawing instead of basing the choice on the word alone. A photo of the face mainly shows shadows and surface lines. It can hide the depth of the ridge and the way the sides are shaped. A cross-section drawing reveals these differences. It is worth seeing where the material projects forward and where it recedes towards the structure. Only then can you tell whether two similarly looking models have a comparable geometry.

The word "double-sided" can describe either the sheet surface or the way the slats are arranged. These are two different issues. A slat with a decorative colour on both sides can still form a single row. Conversely, two rows can be built from different finish variants if the system allows it. When talking about a fence, it is therefore worth using full descriptions. That way the metal slats will arrive in the ordered version, and the expected degree of screening will follow from the actual arrangement. A decoratively double-sided variant has a finish intended to be viewed from both sides. However, its exact description must be established. Do both surfaces have the same colour? Do the gloss and texture match? Is the woodgrain decor also present on the back? The word "coated" alone does not answer all these questions. The sheet may be protected on both sides yet look different on the front and the back.

Making fence slats to measure allows the infill to be matched to the design and limits cutting on site. However, the benefit only arises when the lengths have been correctly established. The planned fence height alone is not always the slat length. Ground levels, the base, clearance and the type of finish also come into play. For horizontal installation, tolerances and accessories are also important. It is worth organising this data before ordering production, because subsequent correction is not always straightforward. For a vertical fence, choose a common reference level. It should correspond to the finished surface or another point adopted in the design. If the ground is not yet finished, allow for the planned layers. Fence slats made of sheet metal ordered according to a temporary ground level may end up too low or too high once the works are complete.
