Types of packing

Packing of finished products is carried out in accordance with the requirements of GOST 7566-94, GOST 503-81 and schemes agreed with customer on. According to the normative document a strip coil shall be strapped to a pallet at least in three positions. For corrosion protection strip is coated with a layer of inhibited grease. The delivery of strips without the grease can be agreed with customer individually. Packing can be done both on vertical and horizontal axis

Vertical axis packing

схема упаковки стальной ленты (вертикальная ось) 1Coils from slitting line, wound on a coiler with plastic or metal strap, are laid on a wooden pallet. If a strip width is less than 50 mm, there shall be at least one strapping through an inner coil diameter, packaging an inner end of the strip.

Strip coils with wooden fillers between are put together in piles. Strips wound on single coilers can be laid without fillers between the coils.

In accordance with the scheme strips are wrapped in packing paper or film and strapped to a pallet by 4 packaging steel straps. To prevent from frontal surface deformation plastic pallets are put under packaging seals. Depending on a packing scheme products can be packed in paper or metal box.

Horizontal axis packing

Required number of CR strip coils with marking tags are laid on a pallet and strapped to each other by one or two radial packaging steel straps (through inner diameter).

Strip coils are set with wooden fillers. Strips wound on single coilers can be set without fillers between the coils.

In accordance with the scheme strips are wrapped in packing paper and strapped to a pallet by 2 and, not less than 4 on forming, radial packaging steel straps.

In order to ensure more efficient cutting of hot-rolled and cold-rolled coils, steel strip (strip) is produced. This type of product is obtained in two ways: by rolling or longitudinal cutting of sheet steel coils. The production of cold-rolled strip is based mainly on cutting, since the price for this type of strip is lower and there are much more people who want to buy it. Cold-rolled strip according to GOST can be produced cold-worked, soft, normal precision, etc. The price for the strip is determined based on the market value for hot and cold rolled steel.

Application area

Hot rolled and cold rolled steel strip is used in the following areas:
Hot-rolled strip is used for the production of pipes – electric-welded and shaped. The clamping tape used for pipe ties is also made of strip.
Steel tape is actively used for the production of construction products. In particular, strip for profile, production of shaped pipes + from strip
Electrical steel tape for cable armouring can be supplied galvanized, non-galvanized, normal or high precision.
Spring cold-rolled strip produced by UMK is used in the production of springs and tools. Softer roll strip (flexible steel strip) is used for stamping machine and equipment parts.
The production of cold-rolled strip is largely focused on the production of packaging, strapping and banding materials. Strapping with steel strap is carried out with special equipment and tools, which you can buy in our company (for more details, see “Packing tool”).
