Brown Composite Handrail System: Low Maintenance
Decks over 400mm off the ground should have a safety barrier or a handrail system.
The post system is a sleeve system. The structural work is carried out in treated timber, including specially sized, treated and sealed posts, which may or may not be concreted into the ground and integrated into the structure of the deck. Normally 2.4m or 3.0m posts are concreted into the ground at 1.8m apart. The post carries up through the deck to 1.2m above deck level. The composite brown sleeve is slipped over the post and rests on the deck. The post skirt is then slid down to hide the expansion gap left between the deck boards and the post. The post cap completely seals the post system (life span of 25 years plus.)
The composite handrail section is made on its flat in an improvised jig for accuracy and speed. The completed composite handrail sections are positioned between the posts resting on steel brackets. They are then screwed to posts. A space of 90mm is normally left between the bottom rail of the handrail section and the surface of the deck with 2 or 3 90mm pieces of spindle used as anti-sag reinforcements.
