Easily Laid with local Crew The replacement is quick, with pre planning and working bay by bay, traffic can be moving again in 20 to 30 minutes for each bay removal and is easy to lay with local labour. Equipment is simple, all lifting can be by manpower and special bolt down socket spanners are supplied, which makes it very difficult to steal or vandalize. |
Markham Dekplank® is I00% designed and manufactured at the Markham Culverts plant in Lae, Papua New Guinea from Hot Dip Galvanised Steel, for long durable life to replace the old bridge deck which might have rotten timber, worn out planks, stolen parts or been vandalized. Dekplank® can be used on all Bailey type bridges with timber decking systems using standard 5 stringer sets. Dekplank® has been designed and certified to accept T44 loading in compliance with Austroads I PNG bridge design criteria when laid across five (5) existing Bailey type stringer sets.
Cross section of Dekplank While the Dekplank® is T44 load capable, the design and condition of the existing bridge may be the limiting factor. The surface has a non-slip Holdek ® running strip and the plates allow free draining across 45% of the width and through the holes.
