Formwork girder H20
Main parameters
mm
The girder is an I-beam with flanges made of solid or spliced wooden bar and posts (walls) made of FSF or FK plywood (wall thickness 24-27mm) installed with a toothed spike in the grooves of the shelves on glue.
Glued wooden girder are designed for load bearing as an element of formwork slab and wall and column formwork in the period of preparation and manufacture of monolithic reinforced concrete structures of interstorey floors, walls and columns of residential, administrative, public and industrial buildings.
It is allowed use of beams as floor beams, elements of wooden roofs (rafters, purlins, struts and underpinnings) for low-rise construction.

Finishing of girders is made by weather-resistant paint compositions. Skips of finishing coating are not allowed.
Durability of the coating is not less than the warranty period of storage and initial operation of the beams.
The products delivery set is determined by the terms of the contract (order) for the supply of products.
Finished products are delivered assembled with final finishing.
Each product is labelled by applying ink to the surface of the product with indicating: the trade mark of the company manufacturer's, logo, size of the product, date of manufacture
Each package is labelled.
Delivery set
Labelling
The beams are packed in packs of 50 or 60 or 100 pieces depending on the type of transport. The packages are tied in at least two places with metal or propylene tape. To prevent damage to the girders in the packages, plastic corners must be placed under the packing tape during packing.
Packages are formed in accordance with the requirements of GOST 19041. The width of the bundle shall not exceed 1150 mm in width and 1150 mm in height. The weight of the packet should not exceed 2 tonnes.
Only girders of one grade and one size are packed in the one package. In case of a small volume of girders delivery it is allowed to pack girders of different lengths in a package, but not more than three lengths, with the ends of the girders aligned on one end of the package.
Packages shall be covered with polyethylene film on five sides.
Packaging
Storage shall be carried out in closed ventilated rooms or under a shelter, excluding atmospheric precipitation and direct sunlight.
Products may be transported by all types of transport in covered vehicles in accordance with the rules of cargo carriage, operating on this type of transport.
When transporting, loading, unloading and storing the products, their safety from damage, contamination and moisture must be ensured. During loading and unloading operations, safety rules must be observed.
Short-term storage of girders in the open air is allowed provided that they are protected from the direct impact of climatic factors.
To clean the products it is not allowed to use detergents containing abrasive materials
Girders shall be stored sorted by type and size, stacked on wooden pads in such a way as to prevent their sagging.
The colour of the girders may change during storage.
