Metal Deck

Surfaces that appear level can be just as dangerous as stairways - perhaps even more so, as less care seems to be required. Poor lighting, cracked or uneven paving or concrete, and the presence of water, oils or other liquids can seriously aggravate the risk of trips and falls that result in physical harm and lost time.

 

When new, chequerplate offers reasonable slip protection, however, the edges wear rapidly creating a deceptively slippery surface.

Where straight walkways exist such as beside conveyors, the metal deck can be spaced up to 150mm between sheets so that either heel or toe contact is achieved.

This allows spillage to pass through the grating walkway and offers considerable cost savings whilst eliminating any chance of slips occurring.

  2. Dimensions

    Vigil Antislip Metal Deck is measured in two dimensions; length ways (A) and width (B).

    Dimension Metric Imperial
    A 200mm 7.9″
    600mm 23.6″
    B 450mm 17.7″
    600mm 23.6″
    750mm 29.5″
    900mm 35.5″
    1200mm 47.2″
    Standard Grades Commercial, Industrial, Offshore


    A:
    Length of Metal Deck: There are two standard lengths; 600mm and 200mm. When laid, each sheet of Metal Deck can be spaced up to 150mm from the next sheet because on a straight walkway it is only necessary for personnel to achieve either heel or toe contact with Vigil Antislip to avoid accidents. By using 200mm sheets, there is less antislip required per square metre, however, there are more fasteners required so installation costs will be greater than if 600mm sheets were being installed.

    B: Width of Metal Deck: As with Stair Nosings, Metal Deck need not cover the whole width of the walkway or ramp. Personnel tend to walk within 100mm from the edges of walkways so it is recommended that Metal Deck 150mm – 300mm narrower than the overall walkway be ordered, ie. if ordering Metal Deck for a 800mm wide walkway, 600mm wide Metal Deck will provide ample protection.
    If there is omni-directional traffic, it is suggested that the Metal Deck is butted up against each other, to avoid slips between spaced sheets The situation is similar with landings where there is turning traffic.

  3. Grades
    GRADE APPLICATION
    Commercial Apply in areas where heavy spillage or soilage does not occur.
    Industrial Designed for external areas where there may be spillage and/or soilage from lubricants.
    Offshore Ideal for areas where there is a high buildup of grease or oil. This surface is the most severe and is not affected by very heavy spillage and soilage of chemicals or lubricants.

  4. Colours

    The color of Metal Deck is not as important as for Stair Nosings or Ladder Rung Covers. Safety Yellow is often used to highlight the safe area, however this may become dirty from spillage and soilage. Because of this, many companies are turning to our alternative colours from the Vigil Antislip range:

    Safety Yellow

    Royal Blue

    Ochre

    Slate/Black

    Rust

    Tropical Green

    Chocolate Brown

    Platinum (also available as Off White)

    Cardinal Red

    Many offshore companies are now purchasing Deck Mark which is Metal Deck with permanent writing and/or symbols on the surface. Apart from eliminating the chance of slips on escape route walkways during an emergency, Deck Mark points personnel to the nearest escape path. This works very well because when running, personnel are watching their footing, not looking above eye level for signs.

  5. Warranty

    How we can offer a 10 Year Replacement Warranty

    As innovators and pioneers in the safety industry, it is important that we lead by example.

    Our production manuals contain the QA/QC requirements for every process. As a basic rule, every production team member acts as a buyer and a seller. When a process is completed, the person who conducted that process becomes the internal seller of the product to that stage. It is then passed on to the next person in the production process – the internal buyer – who checks all specifications, etc. to ensure the previous process was carried out in accordance with requirements.

    The product continues through the production process that way, being rigorously checked by the ‘internal buyer’ at every stage.

    Every process is also signed off by the operator on the Job Card. This ensures quality is maintained and checked throughout all processes rather than just at the packaging stage. All raw materials are checked upon receipt, resins are tested for hardness and so on.

    When the products are completed, the Job Card number becomes the Warranty Number and this is stamped on the underside of every product so it can be traced should there ever be a future issue.

    The 10 Year Replacement Warranty Certificate provided with every Class 1 is signed by the Managing Director and the Production Manager. The Job Cards are archived for a minimum of 10 years so they may be recovered and the production process traced if necessary.

    Please Note : All Test Certificates are available upon request.

     

    To remove the risk from buyers of purchasing inferior quality antislip products, a warranty period of 10 years should apply. It should also be a reasonable warrant; with few exceptions and the promise of replacement of inferior products. Vigil Antislip products are warranted against delamination, chemical attack, wear and corrosion when in normal use for a period of 10 years.

OPEN GRILLE /GRATING (Stainless Steel Saddle Assemblies)
Metal Deck may be installed with stainless steel or galvanised Saddle Assemblies by one person. This is also the method to install Metal Deck where access under the grating is not available.

Tools

•  Variable speed drill (electric, pneumatic or battery)

•  P-3 driver for drill

•  1/4″ High speed steel drill bits

•  Steel rule

•  Centre punch

•  Hammer

•  Artline pen or similar

Safety Clothing

•  Safety glasses

•  Ear muffs

•  Safety boots

Fasteners

Stainless Steel Saddle Assemblies. (Part No: 12-210). Consisting of :

•  1 pce M6x50mm Pan Head, Phillips drive S/S metal thread

•  1 pce S/S universal saddle

•  1 pce S/S 6mm Nyloc locking nut (optional)

Procedures

  1. Insert the P-3 driver into the drill chuck and tighten
  2. Lay the sheets of Metal Deck in the desired positions ensuring that gaps are equal and the walkway or ramp is completely protected
  3. Mark the correct position for the holes on the surface of each sheet of Metal Deck. The optimum position for holes is centrally between the transverse and longitudinal grating bars. Try to mark the surface so that the holes will be more than 40mm from any edges of the Metal Deck
  4. Mark the top surface of the grating along the edges of each piece of Metal Deck so they can be returned to the same place after drilling
  5. Turn each sheet over and mark the underside with a number and an arrow so that the correct sheet is returned to the correct position, facing the correct way after drilling
  6. Measure the distance of each mark from the edges and, using these measurements, make reciprocal marks on the underside of the Metal Deck
  7. Using the hammer and centre punch, make an indent on the marks which are or the underside of each sheet
  8. Drill 1/4″ holes using the indents to direct the drill bit. Always drill from the underside through to the antislip surface
  9. Insert the metal threads into the recently drilled holes so that the head is on the antislip side
  10. Screw the pre-threaded saddles on to the metal threads protruding from the underside of the Metal Deck (3 – 4 turns will suffice)
  11. Return the Metal Deck to the original positions and swivel each saddle around until they fit through the holes in the grating
  12. When all saddles of the first sheet are through the grating and the sheet is in its original position, stand on the Metal Deck and insert the P-3 driver (on the drill) into the head of one of the metal threads
  13. Reach some fingers through the grating and rotate the saddle 90 degrees so that it will lock up under the grating
  14. While holding the saddle in this position, activate the drill and slowly tighten the metal thread into the saddle
  15. Continue tightening the metal thread until the saddle assembly and corner of Metal Deck are secure. (Approx. 5ft/lb)
  16. Repeat procedures 12-15 for the other metal thread / threads on the first sheet of Metal Deck and continue onto the next sheet

Please Note

To avoid any accidents, block traffic flow through areas being worked on.
