How can QMS help with your commercial line marking? Over the years, our teams of highly skilled line marking specialists have worked on a wide range of commercial projects, from car park at Tesco Extra to helping Lidl organise their largest storage and distribution centre in the world with comprehensive walkways and more, read more about it in our latest case studies: ‘Lidl Exeter regional distribution centre’.
This is why we, QMS, the line marking innovators, pride ourselves on knowing and understanding exactly what is needed when planning internal markings for your warehouse, factory, or other commercial space.

Before you start, the first critical step is planning the overall layout of your warehouse. Consider the workflow, vehicle movement, and employee traffic. Are there specific zones for loading, pedestrian pathways, or restricted areas?
Once you know the overall layout, you can make informed decisions about if the existing plan has any potential hazards and congestion points. Your goal should be to minimise confusion while maximising operational flow.
Once you have decided on the floor’s layout, you can work with our talented team to determine which line markings need to be installed where.
Before we install the warehouse’s markings, the surfaces need to be thoroughly cleaned and free of debris, dust, and oils. If the floor has cracks, potholes, or other damage, these must be repaired first.
At QMS, we use our captive shot blast machine with a dust collector to prep the surface, meaning that you don’t have to spend time moving your stock around or worry about contamination of food produce.
Our prep process has been designed to ensure the materials adhere to the surface and is a crucial part of our 60 month guarantee.

When it comes to choosing the right line marking solution, you’ll be spoilt for choice with QMS. Depending on the specific needs and the level of traffic in the area. Options include:

Colour coding is a universal system that helps everyone in the warehouse easily identify specific zones, safety hazards, or pathways. Consistent use of colour-coded markings can improve safety and efficiency. Here’s a breakdown of essential colour guidelines:
| Line Marking Colour | Used For | Used For |
|---|---|---|
| Yellow | Pedestrian and traffic flow | It signals a safe zone for workers on foot, helping them avoid accidents with moving machinery like forklifts. |
| Red | Fire and emergency equipment | Ensures that in case of an emergency, employees can quickly locate these critical resources. |
| Blue | Mandatory instructions | Blue markings often highlight areas where specific actions are required, such as personal protective equipment (PPE) zones. They serve as a visual reminder for workers to follow safety protocols. |
| Green | First aid or safety zones | Green markings denote safety zones or first aid points. These areas are crucial in case of accidents, providing a clear path to medical equipment or help stations. |
| White | General storage or equipment | Used to outline general storage areas or spaces for equipment. It creates a clear boundary that organises warehouse storage effectively, ensuring items remain in their designated spots. |
