With Pretec’s guides, you’ll get more information about our products, their areas of use, maintenance, and range.
Concrete screw
The concrete screw is used for all types of concrete fastening. It is normally used for applications with medium load in concrete, solid brick, hollow brick, or stone surfaces.
The concrete screw can also be used in compression-resistant natural stone and green concrete.
PC-Coat
A coating that provides optimal corrosion protection for steel!
PC-Coat is our well-known surface treatment, used in many industries to ensure the necessary lifespan in demanding environments. The treatment creates synergy effects, which give the system a longer service life.
Post-installation in concrete
Steel structures often need to be fastened into concrete structures afterwards – everything from suspending installations to fixings for beam supports. There are many types of fastenings: expansion anchors, concrete screws, chemical anchors, etc. Here, it’s easy to overlook an important aspect: whether the concrete should be considered cracked or non-cracked.
Drillpipe
Drillpipe PD55 is our efficient pipe umbrella and reinforcement system. To be able to use the PD55 system outside the theoretical tunnel contour, preparation of the face is necessary.
Having the right drilling settings is crucial for the PD55 system. Follow our settings here.
Tightening torque
Assembling a bolted joint is about more than just tightening a screw – every step must work 100% to ensure a safe and durable result. The difference between theory and practice is significant, and there are many factors to consider throughout the entire process, from design through purchasing and storage to installation.
Hot-dip galvanizing vs. Zinc flake
To help you choose the right surface treatment, we’ve put together a clear comparison between two common options: hot-dip galvanizing and zinc flake coating. These two treatments differ in method, level of protection, appearance, and areas of use.
