SCHRAUBFREI

SCHRAUBFREI, which translated means “SCREW FREE”, offers landscape gardeners and private garden owners an innovative and patented plug-in system for visual protection fences. The system works without screw connections and is therefore very easy to assemble. The overall lengths and heights can – and this is unique – be freely selected. The five variants Type 7, Type 7/25, Type 9, Type 9T and Type Rhombus are currently available.

The posts of the visual protection fences from SCHRAUBFREI are made of steel, are hot-dip galvanized and optionally powder-coated. They can be used both as a starting post – then the backs have no holes. Or they are used as double or corner posts – then the backs are provided with two holes each.

In addition to the delivery of visual protection fences as warehouse goods, SCHRAUBFREI is also the right contact for individual special solutions. For example, when it comes to corner or slope constructions or when customers want special post colors.

Idea

Markus Müller, a freelance master in gardening and landscaping, has often had to do with the construction of visual protection fences in his 30 years of professional experience. And because he was often annoyed about the cumbersome structure and the specified lengths and heights, he developed his own plug-in system for visual protection fences in 2014 and named it SCHRAUBFREI, which translates to “SCREW FREE”.

What does SCHRAUBFREI mean

The plug-in system from SCHRAUBFREI consists of steel posts and a stainless-steel insert element. This is where the visual protection planks, made of natural wood, are located. The advantages for landscape gardeners and private garden owners are: No tools, no screws, no additional wood protection and therefore no great effort.

Freely selectable length & height

Another advantage of the privacy fences of SCHRAUBFREI is the freely selectable construction length. This is because the planks, made of natural wood, are supplied in the length desired by the customer. Alternatively, the planks can be sawed precisely on site. In addition, the construction height is also variable, as the posts can be easily reduced to the desired height.

Products

All visual protection fences – type 7, type 7/25, type 9, type 9T and type Rhombus – consist of the three elements: posts, inserts and protective planks. Because the posts of the visual protection fence system are made of hot-dip galvanized steel, a separate post shoe is not necessary and the posts are directly embedded in concrete. In addition, SCHRAUBFREI offers suitable base plates that can be screwed on flat surfaces. Corner solutions and posts for wall connection are also available.

Stainless steel slots with side openings are placed in the steel posts. These openings, which vary in size depending on the type of product, hold the protective boards securely and significantly determine the visual appearance.

The visual protection planks are made of Douglas fir wood from the Black Forest in Germany or stick-glued wood from high mountain larches from Austria. The types of wood used are natural and very durable.

FAQ

Do you have questions about SCHRAUBFREI products? Then you will find the right answers here.

How much does a visual protection element cost?

Since the width of an element is freely selectable with SCHRAUBFREI, the element price depends on the desired plank length. Please note that the price varies only with the plank length, the posts have the same price for each plank length.

Where can I buy SCHRAUBFREI?

All necessary materials for an attractive and durable visual protection fence can be purchased directly from SCHRAUBFREI. Prospective customers will receive a detailed cost offer including an indication of the delivery costs.

Why are the SCHRAUBFREI posts under the powder coating hot-dip galvanized?

Hot-dip galvanizing is the only reliable and durable corrosion protection of iron outdoors. All SCHRAUBFREI posts are basically hot-dip galvanized. Upon customer request, the posts are also available powder-coated.

Why is the powder coating sometimes not even?

High-quality hot-dip galvanizing has a high layer thickness, which is not always flat. In relation to hot-dip galvanizing, the powder coating applied is very thin. Thus, the unevenness of the thick zinc application sometimes appears on the powder-coated surface. However, this is not a defect in the posts.

Do the visual protection planks have to be purchased at SCHRAUBFREI?

No. The planks do not always have to be purchased at SCHRAUBFREI. Prospective customers are offered the exact cut per plank at a meter price per plank and customers receive at least one plank per field without any charge.

Can doors and gates also be ordered from SCHRAUBFREI?

No doors and gates can be ordered at SCHRAUBFREI. However, as the width and height of the visual protection fences are easily adjustable, customers should install a standard gate and simply adjust the width and height of the SCHRAUBFREI- fence accordingly.

Why is hot-dip galvanizing better than galvanizing?

Hot-dip galvanizing is up to ten times thicker than galvanizing and therefore protects the iron much more effectively and for a longer time.

How high can a SCHRAUBFREI privacy fence be erected?

The SCHRAUBFREI posts are 239 centimeters long. Of this length, about 50 centimeters are provided for integration into a foundation and about 10 centimeters for covering over the foundation (earth or paving). This results in a maximum fence height of about 180 centimeters. This is the same for all models. The inserted boards always cover about 180 centimeters.

If you create a concrete base under the privacy fence, for example from commercially available deep curbs, which should be 8 centimeters wide like the posts, the total fence height can be increased to about 190 centimeters. You achieve this increase because the posts do not need to be so deep in the foundation, since the space between the ground surface and the lowest fence board is filled by the curb. Overall, the post and thus the fence can be higher.

In addition, post extensions are available from SCHRAUBFREI. With these 80 cm long extensions, which can be force-fitted over the lower ends of the posts and fixed with screws, a maximum increase of 30 centimeters can be realized. With this variant, too, a base should be provided under the privacy fence. The described type of construction is especially suitable in case of different height of the ground in front of and behind the fence.

How wide can you build SCREW-FREE privacy fences?

Basically, there are two approaches to this, namely the technical and the aesthetic. According to the formal conception of SCHRAUBFREI founder Markus Müller, rectangles placed on edge have a more exciting effect than rectangles placed horizontally. Narrow fields that are higher than wide have a noble effect.

Furthermore it can be said: Since inlaid boards are natural products, shorter planks behave more calmly and retain their shape better than longer planks. This fact should definitely be taken into account when planning the field width.

Irrespective of the two aspects mentioned above, here are the notes on maximum possible widths: For the different types of privacy fences (7 – 7/25° – 9 – 9T – Rhombus), different maximum field widths must be observed due to the different dimensions of the planks. In the case of Douglas fir planks, 20 millimeters thick and used in types 7 and 7/25°, the maximum width is 200 centimeters. For Douglas fir and type 9 boards, as well as for the rod-glued larch planks 23 millimeters thick and type 9T or type Rhombus, the maximum width is 230 centimeters.
