The Civik Zink is special outdoor version of Arke’s Civik spiral staircase kit. The metal parts have been specially coated with zinc through a hot dip galvanisation process to prevent rusting. The treads have holes punched into them to provide a rough slip resistant surface. The Civik Zink staircase is easy to assemble and most people manage to do this in a single day using standard tools.
The Civik Zink spiral staircase comes in different sizes and can be adjusted to suit most houses. For more information please read the height and layout tab. Otherwise the most common queries about the Civik spiral staircase kit are:
What comes in the box?
A landing plate to fix to the upper floor
A centre pole and base plate
Treads
Tread spacers
Balusters
Handrail
Two wall brackets
Written installation instructions and a DVD
What are the main parts made from?
The landing plate and treads are made from pressed steel. They have a galvanised zinc finish to prevent rusting and have been punched with holes to provide an anti slip surface.
The balusters and tread spacers are made from steel tube. They have a galvanised zinc finish to prevent rusting.
The handrail is made from PVC (plastic) and is black in colour.
How is the delivery made?
The Civik spiral staircase is supplied in kit form. It is shipped in a large plywood box on a wooden pallet and depending on the number of treads ordered there may be a few smaller cardboard boxes as well. The delivery is made using a large vehicle with a tail lift and a pump truck because the main box is too heavy to be lifted by hand. The driver will take the goods off the lorry and deliver them to the roadside outside your property, or as close as possible if you live on an unmade road. From there you will need to provide the means of bringing them into the building. If you need to do this by hand you can do so only by opening the box and carrying in the pieces inside. It is not possible to move the complete box by hand as it will weigh at least 150kg.
How can I tell if it will fit my house?
You need to take a few measurements and then carefully read the information we give on heights and layout and fixings. If you have any questions please do not hesitate to call our technical sales team on 0800 098 8778. We're here to help!
Will my new staircase meet building regulations?
Approved Document K from the Building Regulations refers to British Standard 5395 1984 part 2 for guidance on the design of spiral staircases. Essentially the standard gives different requirements depending on where a spiral staircase is going to be used. For example the requirements for a staircase in a private house are different to those for a staircase in a public place. Even within a house the requirements can change because a staircase up to a small loft conversion can be smaller and steeper than a staircase going from ground to first floor in a family house. If your installation needs to comply with building regulations then you need to find out which category of spiral staircase is right for your situation (ask Building Control). Providing you buy the 1600mm diameter model, and you assemble it so that the rise per step is less than 220mm, the Civik Zink will meet the requirements of a category A or "Small Private" stair. It is your responsibility to determine whether or not this will meet your requirements.
Accessories for the Civik Zink spiral staircase kit
In addition to the Civik Zink spiral staircase kit there are some accessories available which you might need to finish your job. They are:
Riser bars for the Civik Zink spiral staircase kit by Arke
Riser bars are horizontal steel tubes which fit between the treads for the safety of small children. You should fit them if children under the age of five are likely to have access to the staircase.

Staircase Height
At the bottom of the Civik Zink kit spiral staircase there is a steel base plate which sits on top of the lower floor. At the top there is a steel landing plate which fits level with the upper floor. The height between those two points is known as the floor to floor height. Different buildings have different floor to floor heights and so the Civik Zink spiral staircase kit is adjustable so that it can fit the exact floor to floor height on your site.
What is the floor to floor height?
The floor to floor height should be measured vertically from the top of one floor to the next.
Floor to floor table
This table allows you to work out how many treads and risers you will need to be able to reach your floor to floor height. The term “riser” refers to the height of each step and the tread is the surface you stand on. There is always one more riser than there are treads because the last riser is the step up from the top tread to the landing plate.
| Floor to floor | No. of risers | No. of treads |
|---|---|---|
| 2100 - 2350mm | 10 | 9 |
| 2310 - 2580mm | 11 | 10 |
| 2520 - 2820mm | 12 | 11 |
| 2730 - 3050mm | 13 | 12 |
| 2940 - 3290mm | 14 | 13 |
| 3150 - 3520mm | 15 | 14 |
| 3360 - 3760mm | 16 | 15 |
Staircase Layout
Once you have determined the number of treads that will be in your staircase you will also need to check whether or not the layout of the stair will be appropriate for your site. The drawings below show the typical layout of a 12 tread (13 riser) staircase. Of course your installation may well need more or fewer treads than this so if you want us to make a specific drawing for you please call our technical sales team on 0800 098 8778. Please bear in mind that the staircase must positioned so that it is at least 25mm clear of any surrounding walls.
Typical layout drawings - Clockwise rotation
Clockwise rotation refers to the direction in which that treads turn if you start from the bottom of the stair
Typical layout drawings - Anticlockwise rotation
Anticlockwise rotation refers to the direction in which that treads turn if you start from the bottom of the stair
The Landing Plate
The landing plate supplied with the Civik Zink kit spiral staircase kit is triangular in shape and can be used to into square openings, or against the side of mezzanines or straight walls. Please note that finished openings/ stairwells must be at least 50mm bigger than the staircase diameter and ideally 100mm bigger.
As you might expect the Civik Zink Outdoor kit spiral staircase needs to be securely fixed in a few key places. Before you buy a Civik Zink Outdoor spiral staircase kit you need to take a close look at your site to see whether or not secure fixings can be achieved. The different types of fixing are:
Staircase plans and instructions
Here you can download drawings and installation instructions for the Civik Zink Outdoor spiral staircase kit:
Base Plate
At the centre of the stair there is a galvanised steel tube attached to a steel base plate, which needs to be bolted to the lower floor. You need to make sure that when you erect the centre pole it is perfectly vertical. If the floor isn't level then put some packers underneath the base plate to compensate. Below are a few common types of floor and ways of fixing to them. Please bear in mind that if there is an under floor heating system present then you will need to be sure that the area is clear of pipes before you start drilling holes:
Concrete
Drill holes as required and bolt the fixing plate down with the standard expansion bolts supplied.
Concrete under tiles
In this situation there is a danger that the weight of the stair could cause the tiles to crack. One solution is to fit some locking nuts so that the base plate is held just fractionally above the tiles. The idea is that the load is imposed onto the concrete and not the tile.
Landing Plate Fixings
At the top of the stair there is a steel landing plate which fits flush with the upper floor. It has a steel apron welded to it which gets bolted to the wall, or side of the upper floor. The typical fixing is as follows:
Masonry
Drill into the masonry and bolt through the landing plate apron with the expansion bolts supplied.
Baluster Fixing Cup
The first baluster is fixed to the floor to prevent the tread from bouncing when you walk on it (all the treads are connected together by balusters for the same reason). The way it does this is with the use of a special metal cup. The cup gets screwed to the floor first then the baluster sits in the cup and a grub screw holds it firmly in place. The exact type of fixing to the floor varies depending on the type of floor. Here is an example:
Concrete floor
Drill into the concrete or screed, fit the plastic plug supplied and then screw the cup to the floor.
Wall Brackets
The Civik Zink Outdoor kit spiral staircase can be freestanding. That is to say that it isn't essential for you to fix it to surrounding walls. However, if there is a wall very near to the staircase then you should bracket the stair to it to help reduce movement when you walk up and down. The positive effect of fitting wall brackets becomes more apparent with bigger staircases (i.e. lots of steps or a big diameter), where movement is most likely to occur. Brackets are most effective if evenly spread. Either find a spot approximately halfway up the stair, or two spots at a third and two thirds of the way up.
Find a position between two treads where the bracket can grasp the baluster and still reach the wall. Drill into the wall, fit the plastic plugs supplied and then screw on the bracket.
