Accessories are an indispensable part of the proper sandwich panel installation. In krs’s offer there is a wide range of different accessories that together make a whole assembling system. Using the krs’s dedicated flashings guarantees a long life of the building.
Our qualified staff will help you to choose the proper flashings.
Installation accessories fulfill several important functions.
Metal flashings are required not only for improvement of final look of the building, but mainly for covering opened core edges as well as joints with windows, doors etc.
Protection against wind, rain or snow is as important as adding a final touch to the esthetics.
We prepared all of the accessories to fit to the panels both technically and optically.
In krs’ offer we have several installation accessories:
Fasteners (screws, fasteners, rivets, load distributors, etc.)
Sealants (adhesive tapes, sealants, gaskets)

Fasteners with a tapered shank (self-tapping screws)
chipboard screw & particle board screw
Similar to a drywall screw except that it has a thinner shank and provides better resistance to pull-out in particle board, while offset against a lower shear strength. The threads on particle board screws are asymmetrical.

concrete screw& Tapcons & masonry screw & confast screw & blue screw & self-tapping screw & Titen
A stainless or carbon steel screw for fastening wood, metal, or other materials into concrete or masonry. Concrete screws are commonly blue in color, with or without corrosion coating. They may either have a Phillips flat head or a slotted hex washer head. Heads sizes range from 0.1875 to 0.375 in (4.763 to 9.525 mm) and lengths from 1.25 to 5 in (32 to 127 mm). Typically an installer uses a hammer drill to make a pilot hole for each concrete screw.

deck screw
Similar to drywall screw except that it has improved corrosion resistance and is generally supplied in a larger gauge. Most deck screws have a type-17 (auger type) thread cutting tip for installation into decking materials. They have bugle heads that allows the screw to depress the wood surface without breaking it.

double ended screw & dowel screw & hanger bolt
Similar to a wood screw but with two pointed ends and no head, used for making hidden joints between two pieces of wood.
A hanger bolt has wood screw threads on one end and machine threads on the other. A hanger bolt is used when it is necessary to fasten a metal part to a wood surface.

drive screw & hammer drive screw
Chiefly used for attaching manufacturers data plates to equipment. Smooth round or mushroom headed with a multi-start thread on the shank, beneath which is reduced diameter shank that acts as a pilot. The screw is fastened by hitting the head with a hammer and is not intended for removal

drywall screw

Specialized screw with a bugle head that is designed to attach drywall to wood or metal studs, however it is a versatile construction fastener with many uses. The diameter of drywall screw threads is larger than the grip diameter.

eye screw & screw eye & vine eye

Screw with a looped head. Larger ones are sometimes called lag eye screws. Designed to be used as attachment point, particularly for something that is hung from it. A vine eye (in the UK at least) is similar to a screw eye, except that it has a proportionally longer shank and smaller looped head. As the term suggests vine eyes are often used for attaching wire lines across the surface of buildings so that climbing plants can attach themselves.

Krs splendid plank – a perfect fibre cement plank for modern architecture
Krs splendid plank is a unique composite of natural fibres bonded tightly in a high-grade silicate structure. This autoclaved, wood-grain and smooth siding plank acquires impressive toughness, yet remains flexible and dimensionally stable. It is cellulose cement plank that contains absolutely no asbestos fibre.
Benefits of krs splendid plank

Krs fibre cement planks
weather resistant
immune to water damage 
 fire resistant 
 not brittle 
 low shrinkage 
 bendable 
 high workability 
 termite resistant 
 non-asbestos

Krs splendid plank achieves the beautiful aesthetic grooves on the building walls with the edged profile of splendid siding. Krs splendid plank is another version of lap siding with stand up the most demanding design. With krs splendid plank, ship-lapping installation is very simple and efficient. There are several designs of edge profiling available that not only provide innovative styles in for example home designs but also long lasting and less worry from humidity, heat, salt spray and flying debris. Primed planks can be coated before or after installation (double coating) with optional acrylic paint.

Corrosion&Abrasion resistance bimetal spraying process

The bimetallic barrel for single screw is a kind of barrel moulding 2-3mm thick alloy coat on the barrel inner wall which has excellent corrosion resistance, abrasion resistance and high working temperature. And its useful service life is greatly improved contrast to the common nitrided cylinder. Bimetal has more obvious advantages when processing special plastics to enhance the abrasion life, such as engineering plastic, fluorine plastics, PPO and etc.

The company product's single/twin screw, uses special alloy powders being sprayed and welded on the screw's ridge, and uses different alloys and welding methods for the screw of different functions.
