Researched and developed by The G&M Group, The M.A.P Safety System boasts  a range of unique design features, including:

  • Flush fitting design mitigating risk of trip hazards

  • Secure fixings to prevent accidental dislodgement or removal
  • Lightweight modular design for quick and easy installation

Highly versatile safety solution

The system can be used in stairwells ranging from 2 – 4 meters in length and of any width. It is also suitable for use in L-shaped stairwells. Openings next to party walls are no problem and the System allows full or partial access for both operatives and materials.

The M.A.P Safety System is installed at the earliest stages of construction; directly after the joists or other load bearing members have been fitted. What’s more, our system can be used in conjunction with ladders or temporary stairs.

Why is safety decking important in construction?

Safety decking is beneficial in a construction project for a multitude of reasons. Its primary function is to safeguard the well-being of construction workers, mitigating the risks associated with working at heights. Here are several key reasons why safety decking is beneficial:

  • First and foremost, safety decking provides a secure platform for workers to perform tasks at elevated levels. This reduces the likelihood of accidents, such as falls from heights, which can result in severe injuries or fatalities. By creating a stable working surface, safety decking minimizes these risks, ensuring that workers can focus on their tasks with confidence.
  • Furthermore, safety decking enhances overall productivity on construction sites. With a reliable and safe platform in place, workers can efficiently carry out their duties, saving time and resources. This translates into cost savings for construction projects and helps meet deadlines more effectively.
  • In addition to protecting workers and improving efficiency, safety decking also minimizes damage to the building being constructed. It acts as a buffer, preventing tools, materials, or debris from falling to lower levels, thereby reducing the potential for structural damage and ensuring the quality of the final product.
