Precautions of Corten Stairs
The Practice Of Corten Stairs
Determine the size of the stairs
Determine the number of steps n on each floor according to the floor height h and the initially selected step height h, n=h/h.
The horizontal projection length l of the flight is determined according to the number of steps n and the initially selected step width b, l=(0.5n-1)·b.
Determine whether to set the ladder axis. For safety reasons, children’s stairwells should not exceed 120mm.
Determine the width of the stair section according to the net width of the stairwell and the width c of the stairwell, a=(a-c)/2.
According to the width d1 ≥ a) of the intermediate platform (d1), the width d2 of the floor platform (d2>a), and the horizontal projection length l of the ladder, check the net length b of the stair depth, d1+l+d2=b. If not, adjust the l value (ie adjust the b value).
Design adjustments
If the interior structure is found to be inconsistent with the design drawings before construction, adjustments should be made according to the existing actual situation to determine the safety and practicability of the corten stairs.
Prepare materials
Various profiles and construction tools needed to make corten stairs should be prepared in advance. And we cannot prepare suitable production materials. We should buy some sporadic materials to spare.
Start construction
According to the design drawing of the attic corten stairs, the important fulcrum points are marked and laid out on site, and the size of the embedded parts is determined.
First deal with uneven walls and sundries.Drill and clean the holes where marked. After the inspection is qualified, the bolts of the steel frame stairs are implanted, and the bolts are fixed in the holes with chemical fixatives.
Installation
Drill holes on the embedded steel plate and channel steel according to the bolt positions, and then install the steel plate. After the steel plate is installed, certain anti-rust treatment should be carried out, and anti-rust protective paint can be brushed.
Then trim the steel plate of the corten stairs to their liking to make it look more beautiful and elegant. After all, the work is done, remove some glue and paint from the surface and clean if necessary. Such a rigid staircase will be installed.
Precautions for indoor construction of structural stairs
In order to avoid the illusion when going up and down the stairs, the height of the first step and the last step of the stairs should be the same as the other steps.
The height of the highest step of the stairs to the ceiling needs to have a clearance of more than two meters, and the minimum is not less than 1.8 meters. Otherwise, there will be pressure.
The distance between the railings
Between the centers of the two railings is preferably 8 cm, not more than 12.5 cm, so as to prevent children from sticking their heads out of the gap.
The height of the armrest
Waist position is 85~90 cm, and the diameter of the armrest should be 5.5 cm.
The height and depth of the steps
The height of the steps should be 15-18 cm, and the depth of the steps should be 22-27 cm. The number of steps is about 15 steps. If it is too high, you may need to set up a stair rest platform.
Stair width:When one side is empty, the net width is not less than 75 cm; When there are walls on both sides, the net width is not less than 90 cm.
Safety
Stair parts should be smooth and round, without protruding and sharp parts. For families with children and elderly people, the slope of the stairs should be slow and the rotation angle should not be too large; the stair treads should take anti-skid measures, such as anti-skid strips, anti-skid pads, anti-skid grooves, etc.
Stair lighting
Too dark light is not conducive to walking safety, and too bright light is prone to glare. Therefore, the light on the stairs should be soft and clear.
Staircase style

How to Maintenance Corten Stairs
Protection from moisture
Corten stairs is a great material for outdoor use due to its high tensile strength, corrosion resistance, and weathering properties. However, proper protection from moisture is essential to ensure that it lasts a long time without rusting or losing structural integrity. The best way to protect against moisture is by applying a coat of sealant or waterproof paint. Once the surface has been sealed, an additional coating layer should be applied to protect against uv rays and water damage. Lastly, regular maintenance, such as cleaning off dirt and debris, should be conducted to keep the corten stairs looking new and attractive longer than expected!
Cleaning
Corten stairs must be cared for properly to last and retain their beautiful orange-brown colour. The easiest way to clean corten stairs is by using a water hose with a light spray setting, or, if you need more pressure, use a pressure washer set on the lowest setting available. Avoid high-pressure washers, as they can damage the surface of your corten stairs. Once you’re done cleaning, apply an oil-based sealer yearly to prevent rusting. Additionally, remember that cleaning may not always restore the original colour of your sheet, and some discolouration may remain, so it’s good practice to maintain them regularly over time.
Applying a protective coat
