 To start ordering your railing there are number of standard procedures every homeowner need to go thru

– Selecting the desired color

– TimberTech Classic series railing is available 6’, 8’ and 10’ sections. Make your drawing and find out how many 6’, 8’and 10’ sections you need. Doing this process try to make all railing sections on a row same size (for 18’ railing section do 6’-6’-6’ from 6’ sections or 9’-9’ from 10’ section and NOT 8’-10’). Please note that glass sections available only 6’. Sections length are considered from center of post to center of post. Therefore, the actual length of 6’,8’ and 10’ section would be slightly less. Since TimberTech Classic series uses same section for Horizontal and Stair railing application there is no need in this stage separate Number of Horizontal Railing sections needed from Number of Stair sections needed (Just consider total number)

– Determine the height of your railing. As per Ontario buildings code:

i. if the deck/porch height above the grade is 5’ and more then your railing’s handrail should be min 42” high from decking surface.

ii. If the deck/porch height from the grade is less than 5’ your railing’s handrail should be min 36” high from decking surface.

iii. If the deck/porch height from the grade is less than 2’, then you allowed to have your deck/porch without railing.
