Box Gutters
A square or rectangular gutter that is used within the boundaries of the roof. It may be formed between a roof surface and a parapet wall or between two roof surfaces. Available with infold, outfold, splashback and squashfold edges. This gutter is usually supported on a box gutter board to improve strength and stiffness and to minimise damage caused by roof traffic.

Industrial Eave Gutters
A purpose made external gutter which is located at the edge of an industrial roof. It is usually supported by heavy gauge brackets that have been designed specifically to suit the industrial eaves gutter shape. When made in larger sizes special attention should be given to minimising oil canning of flat surfaces by adding extra ribs into the design.

Trough Gutters
A half round segmented gutter formed into a trough. It is formed between a roof surface and a parapet wall or between two roof surfaces and is available with infold, outfold, splashback and squashfold edges. Usually supported by heavy gauge straps, trough gutters are very efficient and have better self cleaning properties than box gutters. In most cases the depth will not exceed half the width.

Pole Plate Flashings
A purpose made flashing used to seal the join between the end of a roof and masonry wall. A “V” groove end locates into either a preformed reglet, or a cut in the masonry wall providing a water resistant join to the roof and wall connection. When installed, pole plate flashings (often called chimney flashings) can either be stepped to conform to brick courses or left straight, for a more modern appearance.

Parapet Capping
A covering used to waterproof and cap the ends of vertical sheets or masonry walls. A stiffening edge or break is often applied to the legs of the parapet cap for a more appealing appearance, and to minimise oilcanning of the steel. Ensure that these recommendations are taken into account when measuring the flashing. It is also important to ensure that water does not pool on top of the cap, to prevent water seeping into the building.

Flashing Drawings
Standard Flashings
When drawing standard flashings, letters describe the dimensions of each plane on the flashing, and numbers describe the included angle. You need to advise us of all dimensions, and identify any angle that is not 90 degrees.
Tapered Flashings
Tapered flashings use the same system as non-tapered flashings. Angles will always be constant throughout the flashing. The dimensions closest to you described as 'NEAR' (as shown in the drawing) have a '1' added to the letter representing the dimension, and the dimensions furthest away described as 'FAR' have the number '2'. Box gutter (1) would therefore be described as shown in the diagram on the right.
Order Methods
Clock Method For Placing Orders By Phone
Commence at the centre of the clock. Draw a straight line from the centre to the number on the clock (1-12) at the required angle, representing the first line of your flashing drawing. Where the pen stops becomes the centre of the clock for the next line. Complete the flashing using this method. For tapered flashings quote nearest edges first. Repeat for the back (use the same letters) unless otherwise indicated.
Page Drawing Method
Begin drawing the flashing at the centre of the page. Describe the direction of the line as you draw it. Advise if the line moves vertically up or down the page, horizontally left or right, or to which page corner. Advise the length of the line. Do this for every line in the flashing. Advise of any included angles.
