Vertical barrier screen (vbs) mesh panels

Successful offeror shall provide VBS mesh panels meeting the physical dimensions listed on the attached drawings. All VBS mesh panels shall be Sefar PETEX 07-3400/60, or equivalent, meeting the minimum specifications and salient characteristics as follows:

1.1 VBS CHARACTERISTICS

1.1.1 The plastic mesh screen shall be polyester mesh woven from 1 mm (0.040 in) monofilament polyethylene terephthalate (PET), 5.84 X 5.84 mesh size. Each monofilament shall have a minimum tensile strength of 80 pounds and minimum elongation at break of 20 percent. The material shall be suitable for use in cold weather and shall be “heat set” at approximately 170 degrees Celsius (347 degrees Fahrenheit) so that it remains primarily dimensionally stable when subjected to temperatures up to 200 degrees Fahrenheit. The mesh monofilaments shall be white in appearance. All strands shall run the full “width” (as labelled on the drawing) of the panel without splicing. It is preferred that all strands run the full “height” (as labelled on the drawing) of the panel without splicing. If splicing is required, there shall be no more than a single splice. The splice shall be oriented along the width and shall coincide with one of the reinforcing sections per the attached drawings. The splice shall be fully encapsulated within the reinforcement adhesive and shall have a tensile strength greater than or equal to the monofilament material.

1.1.2 The vinyl edging and reinforcement support strips covering the mesh panels shall be an adhesive equal to 3M Hot Melt 3764. It shall be thick enough to cover the plastic mesh screen and thereby completely encapsulate it, with a 0.035 inch minimum thickness covering the mesh on each side. Edging material shall cure firm and have an overall finished thickness not to exceed 0.100". Reinforcement strips shall be applied to both sides of the mesh at all locations.

1.1.3 Dimensions shown for perimeter edging and reinforcement strip locations are to the “critical edge”; applied reinforcement strips must fall where dimensioned after application is completed. All dimensions shown on this sheet shall be met within plus/minus 1/8” typical.
