Key Features

Building Code Compliance
Off the shelf Compliant with Level Entry requirements of NZBC E2/AS1 ( - Concrete Slab) and MOE Weathertightness Design Requirements for New Schools, Version 3, Sept 2020.

A. A minimum width of 200 mm and minimum depth of 150 mm Y
B. A maximum length of 3700 mm Y (sections have a provision for an outlet every 3000 mm)
C. A 1:200 minimum fall along length of channel towards a drainage outlet Y (Built into the system, no need to scree in fall after installation. Zero gradient channel is available as an option where there is a depth restriction. e.g. Slab foundation.)
D. The channel discharging to the surface water drainage system via a sump Y (In-line sumps are provided as an option therefore no need to install a seperate sump)
E. Grating, in accordance with Tables 21 and22, over the channel Y (Grating is manufactured with 316 Marine Grade Stainless Steel or Fibre Reinforced Polymer)
F. Grating is supported independently of the door frame Y (12mm continuous minimum gap)
G. Grating that is removable to allow access for cleaning Y
H. Grating that is specifically designed to accommodate imposed loads Y (System can be designed to support vehicles)
I. Grating has gaps sized to prevent the wheels of wheel chairs or mobility aids entering or being trapped Y (8mm maximin gap in Grating) 
J. Grating has continuous gap of 12 mm minimum from door frame and wall cladding Y 


Built-in-Longitudinal and Cross Fall: No Need to Form Channel &/or Scree in Fall during Installation

Easy to Adjust Run Length with 3000mm Telescoping Channel Sections:
The Standard Section Length is 3000mm. Shorter Channel Sections are supplied (500mm, 1000mm, 1500mm, 2000mm 2500mm) for runs under 3000mm which are cut to length on site.

For runs over 3000mm the shorter channel lengths (500mm, 1000mm, 1500mm, 2000mm 2500mm) can be telescoped into the next 3000mm section. 

For Example if Run Length is 3600mm the Section 1 - 1000mm & Section 2 - 3000mm Lengths are supplied. Section 1 is then telescoped into section 2 by 400mm (4000mm less 400mm = 3600mm)      

Adjustable Support Systems: Flexible Modular system: Height, Width and Grate Width adjustment during installation to create 12mm mimimum gap between grate and varying building line

Support Systems are spaced According to Required Loading: Support Systems which are cantilevered and directly supported with a leg can be spaced at 250mm intevals (Vehicle Traffic) or wider intervals where "lighter traffic" will be located. Load Strength where it is required and Significant Cost Savings where "Strength" is not required.

In-Line Sump: No Need to Seperate Catch-Pit

Corner Units: Interchangable Internal and External

Range of Grating:

Wedgewire Stainless

Laser Cut Stainless

FRP (Fibre Reinforced Polymer)
