Stairs are one of the most critical and error-prone sections of any construction. To avoid stumbling, each ascent (vertical height) and run (horizontal size) must be constant. When designing, building, and installing stairs. Whether wood stair or composite stair, safety must be considered.
How to install composite board stairs
At some time during the day. And you climbed a flight of stairs without much thought to composite decking stairs. Or not considering the costs. They are crafted with love and skill. Humans struggle to manage stairwells. And stair safety has been studied extensively. Even so, stairs are a major risk of injury both inside and outside the home. Building a staircase that does not harm people takes skill and forethought.
Divide the vertical and horizontal space evenly between the two heights, considering the size of the pieces you will utilize. A composite stair set’s relevant parts are:
In this case, they support the stairwell on both sides. 2×8–2×12 pieces of wood with right-angle notches The stringers are normally 12 inches apart.
This is the horizontal part of the stairwell. They must be at least 10 inches broad to be safe. And 1 inch thick to support the weight of a person standing on them.
The vertical pieces between each tread. Outdoor stair building does not necessitate them. But they complete the composite stair design. And keep feet from sliding under the treads. They must be at least 1/2 inch thick if used.
Contrast the facade with the vertical distance between each tread surface. To build stairs, you must first measure the distance between the horizontal planes. Then divide by eight to get the required steps. Because adding one inch of tread thickness. It will be below the maximum ascent.
If not, add one more step to the total and count from there. The lateral space is more flexible, allowing you to extend it to the necessary ten inches of tread. This is required for safety and is generally painful on-site. So much so that I buy pre-cut stringers and build my projects around them.
Problems with wooden stairs
Mold can grow on ancient wood boards. Wet wood is a slipping hazard. Moreover, the board tends to shrink, bend, or alter size with time. The board’s edge may twist and grab unwary toes, causing a trip hazard.
Fasteners such as nails, screws, and bolts may loosen when the wood changes size. This exacerbates the problem of uneven boards and loosens their grip on the deck. Loose planks on the deck surface are annoying, but loose planks on the deck stairs are dangerous. Using composite boards on the steps can help reduce safety hazards as the deck ages.
Checklist for Composite Deck Stairs
Composite decking combines synthetic (plastic) and organic (wood) components (such as wood powder). Composite decking is less perishable than wood and does not mold or mildew like wood due to its synthetic nature. It also has reduced water incursion path. The decorative board will be more moisture-proof if completely covered.
When building stairs, look for stringer spacing that preserves the 12-inch centerline separation. Only one decking board is needed per tread, resulting in a cleaner aesthetic and easier installation.
Remember that boards wider than 12 inches but thinner than an inch are fascia boards and cannot be used as treads since they cannot bear the weight of a person standing on them. But they can be risers or kickplates.
The capping protects the decking board against moisture incursion. Because some capping is rough and slippery, use capped composite decking. A waterproof overlay that surrounds the decking board.
Stairs made of high-quality composite decking with these features will be safer as your deck ages. Moreover, they will be more fashionable, like those on interior staircases.
