Steel engineering

Highly-solid, highly-reliable and a high load-bearing capacity

Tested quality in the field of structural steel engineering: where people work and live we do not accept compromises.

If it is about the steel frame of a bank tower or the basic construction of a factory: where many people work and live the consequent obeying to technical requirements is a must. It starts with the minutest elements- our products guarantee connections that are capable of bearing and that meet all of the requirements.

Overhead Line Construction

So that every shot is snug, so that every worker is safe

Optimal commodity perfectly packaged, perfectly picked: We sort, you can work easier.

We are well versed in overhead line construction since; after all, we are one of the leading suppliers of fasteners in the German speaking part of Europe. This is not only because the strength of our fasteners is optimally adapted to the needs of overhead line construction with its widely fluctuating loads. The strong market position is neither only because our warehouses are well equipped - even for larger projects ...

Mining and Tunnel Constructions

Specialists for the protection of people and machines

The challenge of mining: safety through supervised quality.

Wherever getting out of the way of dangers is no alternative at the workplace because you are stuck under the ground during mining and tunnel construction, safety is the top priority, since it concerns many lives in a very confined space. Consequently high demands are made on the components that are used for mining. Of course, our fasteners and machine parts for mining and tunnel...

C-Part-Mgmt.

With the client for the client

C-parts optimation: instead of a rigid system from the outside rather a flexible action from the inside.

It has been clear for decades that the acquisition of c-parts such as stationery and office supplies, paper towels, screws, nuts or tools entails a great expenditure. It is hence even more expensive for companies to cover the costs of intern processes like order, purchase, controlling and incoming inspection than the ordered part is actually worth...

Chemistry

Highly resistant and highly safe

Screws and fasteners that keep our promises: best goods quickly in situ.

100% final inspection. That is one of our principles for the chemical industry. Whether it is about commercial refinery or reactor plants, about tankers during the transport or the repair of a pipe connection- every single screw has to meet the expected requirements. If rejects or only slightly wrongly designed goods are used, the weal and woe of people and nature are in danger...

Mechanical Engineering

We are as specialised as you need it

More than 50,000 products for a diverse line of business.

In one case it is about the hexagon socket screw at the motor unit the tension of which resists, thanks to safety devices, the strongest vibrations. In another case client standards need to be kept in order to avoid unpleasant surprises for the producers. In one case the insert of a component in a machine tool requires the highest precision, in yet another case it is all about a safe but ...

Magnetic plug systems

Life insurance for your gears

Magnetic plugs: irresistible adherence for a ferruginous abrasion.

It is not without a reason that gear producers are nearly as pedantic as producers of semiconductors as far as dust is concerned: highly precise gears might already have difficulties dealing with minute particles as everything is coordinated too well. Magnetic plug components from SDU make sure that this stays that way even after a long operating time since your magnetic systems collect a huge part of the inevitable abrasion that is produced. Magnets ensure the corresponding adherence in our drain plugs and at the filtration sticks...

Special Elements

The whole variety of metal working

There is (almost) no impossibility: our special parts are as diverse as your requirements.

It starts with overlong and exactly fitting shanks and does not stop with unusually curved exhaust pipe mountings: even the diversity of technical norms of our times cannot cover the entire range of components needed for the solution to a technical problem. Furthermore, new ideas for products...
