How to Build Exterior Wood StepsBuilding steps used to require complicated measurements and difficult angled cuts, but precut pressure treated stringers today have made the job much easier. This article series explains critical safe-construction details for decks and porches, including avoiding deck or porch collapse and unsafe deck stairs and railings. You may require stairs to get from the yard to the deck, from the deck into the house, from one deck level to another. When they are needed, stairs can also add a welcoming, visually appealing element to a well-designed deck. Deck stairs may not have the glamour and character of a fine interior stairway but they do pose the same risks and require the same level of care regarding safety, m This article series provides the basic information you need to design and build attractive, functional, and safe stairs for your deck. Our photo at above left shows a stair stringer and construction design that tells us the builder may have had trouble figuring out just how to attach and support these steps. This deck access stair that may be unsafe due to its age, connections to the deck structure, and the absence of guardrails and handrails.
The need to add support at mid-span on this stair could have been avoided and the handrailings would have been more secure if the vertical railing post at mid span in the stair had been brought to ground level and secured to a pier.
The stair at above right was built by the website author and had to cope with a sloped entry point at the lowest step and an interrupted railing to permit access from the uphill side of a drive.
As parts of a house go, stairs are dangerous places because of the risk of tripping and falling. This discussion is followed by links to articles giving more detailed codes & specifications for guardrails and stair handrails. A handrailing is placed along stairs to assist someone climbing or descending the stairs and to help arrest a fall should the stair user trip. At left our photo illustrates both guardrailings (red arrows) and the handrailing along the deck stairs.
A deck guardrailing and a deck stair handrail and guardrail may not be required in some code jurisdictions unless your deck surface is 30 inches or more above ground.
Our photo (left) illustrates construction of a large deck to be used as a performing stage at the SummerBlue Arts Camp, Two Harbors MN. In the photo at left, my friend Paul Galow is standing on a deck he's built with no railings - happily he later added them. Watch out: as we report at TABLES of ACCIDENT FREQUENCY by TYPE more people are hurt and lose work time due to stair falls than just about any other hazard. At SLIPS, TRIPS & FALLS, EXTERIOR STAIRS we catalog a litany of stupid tricks that assure people are eventually going to fall down an exterior stair. Adding injury to the insult of unsafe stairs is an improperly constructed guardrail or more often, an improperly constructed handrailing along an exterior deck or porch stair. Continue reading at DECK STAIR BUILDING DETAILS or select a topic from the More Reading links shown below. The Stairway Manufacturers' Association, (877) 500-5759, provides a pictorial guide to the stair and railing portion of the International Residential Code. Part 1 of deck stair building (below) outlines the basic codes & specifications for deck or porch stair construction. But as we warn below at Warnings about Unsafe Deck & Porch Stairs by their very nature, stairs can be dangerous, and they are a primary site of household accidents.
The tread depth shall be measured horizontally between the vertical planes of the foremost projection of adjacent treads and at right angle to the tread's leading edge.
Guardrails are also required along stairways but most codes permit the same structure to serve both purposes. This stair handrailing is not correctly built: it uses a 2x6 on flat and is not graspable along the stairway.
If you build a railing with horizontal members (such as in the illustration at right), which is perfectly legal in many areas, it is almost inevitable that children will want to start climbing the railing. We describe typical hazards such as slippery algae, snow, ice on steps, uneven or damaged treads or risers on stairways, or loose flimsy stair railings or deck guardrails.
Part 2 of this article provides step by step details for laying out and cutting the stair stringer, attaching the stair stringers to the deck or porch, cutting and installing stair treads & risers. Specific requirements vary from place to place, however, so be sure to check your local code.
Some building codes are more flexible for exterior stairs than for those inside the house; some are not. Beside it, the prefab exterior stairs are also available and it can complete that prefabricated construction. Like the one besides, the white curved roof is arranged on the wooden truss to make it strong.
And it will be the same with the prefab outdoor stairs but it doesn’t need the crane.The prefab outdoor steps for the eyebrow and curved will be different than the minimalist. As well as for the straight prefab stairs outdoor or the spiral stairs are totally different. It is easy to choose the tapered, triangle, curved and maybe the colonial prefab dormersor exterior decor.
