U channel is a three-sided profile usually with square corners, shaped like the letter “U”, and used to cap, guide or edge various materials...
It is an extruded profile with two parallel side walls and a base, designed to fit over the edge of a board, panel or similar object. U channels are commonly used for capping edges, creating sliding tracks or acting as trim. At MKM Extrusions, U channels are made from rigid PVC and are available in the colours black or white. They come in various different

U channels are often used for capping, sliding track, edge protection or other purposes where a channel-shaped profile is needed...
The three-sided shape of a U channel allows it to fit over the edge of materials such as boards or panels. It can serve functional or finishing purposes depending on the context. Common applications include panel edging, protective capping or acting as a guide for movement. At MKM Extrusions, U channels are manufactured from external grade rigid PVC and are available from

Plastic strip is a flat, two-dimensional profile that is often used for edging, spacing, or covering surfaces such as boards and panels...
Also known as PVC flat bars or PVC strips, these profiles are versatile in use. They can serve as edge protectors, gap fillers, spacers, cover strips and many more applications. The profile has two dimensions in its cross-section (width and thickness) which makes it suitable for finishing flat surfaces with a clean edge. At MKM Extrusions, plastic strips are available

It depends on the application but plastic corner trims are sometimes attached using self-adhesive tape, glue, or mechanical fixings...
There are three main methods to consider when fixing plastic corner trim in place: 1. Self-Adhesive Tape Stock profiles are not supplied with adhesive tape. For larger custom production runs, it may be possible to apply double-sided tape during the manufacturing process. This allows for an invisible bond without visible fixings. The type of tape used depends on surface

For best results plastic trim corners should cut using a fine-toothed saw. The finer the teeth, the smoother the cut. Cutting slowly helps reduce the risk of chipping...
Plastic trims, such as angle trims or flat strips, are made from external grade rigid PVC and have a fixed shape. To achieve a clean result when cutting corners, it’s best to use a fine-toothed saw. The finer the teeth, the smoother the cut. Always secure the trim properly before cutting, and use steady, controlled motion. For very

A corner trim is usually a 90-degree L shaped profile which is used to protect or finish corners and edges. Some other forms are available such as corner joints...
These profiles are designed to cover and neaten external or internal corners, offering a defined finish and helping to reduce visible wear on edges. They have a fixed L-shaped form and are often referred to as plastic angle trim or L shaped plastic trim. At MKM Extrusions, corner trims are made from external grade rigid PVC and are suitable

Square tubing is typically called box section, square tube or square plastic tube, describing its four-sided, box-like shape...
These plastic tubes have a box-like cross-section with four flat sides and right-angled corners. While often called “square,” some of these profiles could be rectangular and vary in width and height. The naming convention typically refers to the general shape rather than exact proportions. At MKM Extrusions, plastic square tubing is made from rigid PVC and is available in

The difference lies in the cross-section: square tubes have equal sides, while rectangular tubes have differing widths and heights...
Both are hollow profiles with four flat sides and right-angled corners. The key difference is that square tubes have the same width and height, while rectangular tubes do not. Despite this, at MKM Extrusions both shapes are referred to as square tubing, based on the overall style of the profile. All profiles in this category are made from rigid PVC and are available

One of the differences is in how they are measured: tubes are defined by their outer dimensions (OD) and shape, while pipes are defined by their internal diameter (ID) as this determines the capacity...
Plastic tubes (whether square, rectangular or round) are usually measured by their outside dimensions and wall thickness. They are often used for protective purposes, spacing, framing, flags and many other purposes. Pipes, in contrast, are often used for transporting liquids or gases and are defined

Extrusions can be identified by their consistent cross-sectional shape and the fact that they are made in continuous lengths...
An extrusion is typically a linear profile with a uniform shape throughout its entire length. It is produced by pushing molten plastic through a shaped die or tool, which determines its final form. Common profile extrusion shapes include plastic angle trims, plastic U channels, plastic flat bar strips and plastic tubing. All plastic trims and profiles that MKM Extrusions offer
