Frequently asked questions

Welcome to our page of frequently asked questions. We have tried to address many of your questions but please contact us if your specific question is not answered here.

A.    Safety flooring for transport is specially engineered to minimize slip risk and provide safe movement in moving vehicles such as buses and trains, all while meeting the required fire and performance specifications for the intended application area. It is often referred to as non-slip flooring, however, this is a misconception. It is designed to minimize the risk of injury in areas that are exposed to slip risks such as mud, water, or ice tracked in from outside the vehicle, or spilled food and drinks.

A.    Safety flooring was invented in 1947 by us, here at Altro.

A.   Safety flooring is a flooring engineered to provide sustained slip resistance, usually with quartz or silicon carbide aggregates throughout the thickness of the floor so that slip resistance is maintained as the floor wears away.

A.    Slip-resistant properties mean a floor has been engineered to minimize the risk that people walking on it will slip, even when contaminants such as water, ice, or mud are present.

A.    Slip resistance is determined in lots of different ways. In the UK and Ireland, the most subscribed-to way to measure slip resistance is with the Pendulum test, giving a Pendulum Test Value (PTV). Watch our video on the Pendulum Test here. A PTV of 36 or higher means that the risk of slipping on that particular floor is as little as one in a million.

A.   Easyclean technology is a resilient coating applied to some Altro Transport products to ensure easier cleaning of the products.

A.    Altro Transport floors are constructed in three layers: the top coat, scrim, and undercoat. This triple layer construction gives our floors greater durability, resilience, and flexibility.

A.    Altro was the first to introduce the hot weld joint, which continues to be the best quality hot weld on the market. The hot weld is designed to tolerate temperature changes and vehicle movement ensuring a fully bonded, watertight and impervious system is in place at all times. Hot welds are permanent and watertight ensuring that separation is prevented. Specialist rubber weld rods are available for use with Altro Transflor Motus.

A.    Altro flooring can be cold welded, and creates a very good seal. Altro does not provide any cold welding products, so please contact your chosen manufacturer for your specific requirements.

A.    Yes – Used in floors, vinyl is highly durable, non-porous, non-shedding and has very high impact resistance, which prevents the cracks and chipping that can trap bacteria. Vinyl is suggested for use as a standard for the transport industry because of its inherent hygienic and safety properties, as well as a far more effective cleaning record compared to carpet. Vinyl is also naturally hygienic – no additives are required, compared to other materials such as carpet which give bacteria and viruses a safe haven.

A.    Altro transport safety flooring works because of the aggregates within the floor. These are designed to maintain contact with a shoe, no matter what contaminants are present on the floor.

A.    Altro Transflor Chroma, Altro Transflor Figura and Altro Transflor Meta are all designed for heavy duty bus. These products are engineered for unrivaled sustained slip resistance and tough durability.

A.    Save time, weight, waste and therefore, money, on your installation by making use of our transport installation services such as our self-adhesive or pre-cut flooring services.

A.    Yes – find our installation guidance here, or alternatively, watch our installation video series here.

A.    Yes – Altro offers industry-leading non prorated warranties of at least ten years, and more for greater thicknesses.

A.    When Altro Transflor products are maintained correctly, we expect them to last much longer than the warranty, and in most cases longer than the general refurbishment lifetime. We can also offer extended warrantees on a project by project basis, based on usage. Please contact us for more information.

A.    As standard, here are the tools you'll need to install Altro transport flooring:
  • Full PPE including gloves and eye protection
  • Utility knife with hooked and concave blades
  • Straight edge
  • Trowel handle and trowel blades
  • Hand roller and large three section roller
  • Heat welding gun with round and HB welding nozzles
  • Trimming knife / spatula and metal trim plate
  • Grooving handle and blade
  • X-acto blades
Find out more information about the tools we recommend and what they're used for in this video.

A.    Altro has a list of recommended cleaning products, including our own AltroClean products and those from our sister company, Autoglym. View our full list of recommended products here.

A.    Slip resistance of Altro floors should last for, at least, the same period as the product warranty. This assumes that Altro’s cleaning and maintenance guidelines are followed.

A.    Each of our transport floors will have its safety credentials clearly stated on the product web page, sample card, and all technical information. The safety credentials we use are recognized and accepted in each region we operate in.

A.    Altro Transport floors are designed and engineered for use for all applications across the bus and rail sectors. Find out more about what we offer for each sector here.

A.    You can purchase Altro Transport floors through your local Altro Transport Sales Executive

A.    Our floors for transport are used worldwide in a range of applications. Read a few of our case studies here.

A.    We recommend that only Altro Transport floors are used in transport applications, as they have been engineered especially for this purpose. Altro floors engineered for construction may not be guaranteed for use in transport applications.
Regular commercial building floors are often not capable of coping with the movement and physical stress that interior materials are subject to inside a moving vehicle, as they have been designed for use in a building. Additionally, these products will often not have the fire behavior needed to pass the required fire safety certification for use inside a vehicle.
The Altro Transflor product ranges have specifically been engineered to be installed in a vehicle, be it a bus or a train carriage, both in terms of these floors’ physical properties and their fire certification.

A.    Some vinyl floors may shrink after installation due to plasticizer migration from the flooring material whereby the plasticizer in the flooring product leaks out, reducing the volume of the flooring material causing this shrinkage. There are a number of reasons that vinyl flooring might shrink after installation, such as a reaction with cleaning chemicals, if the wrong type of adhesive is used and water ingress happens, or even unstable temperature in the installation area.

A.   We recommend that a strong dilution of alkaline cleaner is used to clean and disinfect organic soiling on your vehicles. Full guidance and tips for cleaning transport floors can be found here.

A.   All Altro Transflor products feature a porous backing material that facilitate good adhesion to subfloors, especially when using adequate wet adhesives (if you are unsure, please contact us for advice on which adhesives to use). Additionally, most Altro Transflor product ranges now are available with our self-adhesive service, for greater ease and speed of installation. The self-adhesive tape offered by Altro has been tested and developed to be compatible with multiple types of substrates and to perform under harsh conditions – please contact us for more details.

A.   Find out more about the different adhesives offered by Altro here

A.   Yes, please find our video guidance on HB welding here.

A.   Altro Transflor products are engineered to be as lightweight as possible, without compromising on other performance aspects such as slip resistance and durability. A lighter weight floor contributes to a lighter weight vehicle overall, which helps to reduce CO2 emissions in service. Use Altro’s self-adhesive service to further reduce weight on your installation.

A.   Work areas must always be kept well-ventilated during installation. A great way to further improve indoor air quality is to use Altro’s self-adhesive service, which minimizes harmful VOC-emissions.
