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

Coils 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.

Integrated Management System

The company has developed and implemented an integrated management system (IMS), confirmed by the compliance certificate. The certificate confirms that CR strip GOST 2284-79 is produced in accordance with the requirements of GOST ISO 9001-2011 (ISO 9001:2008), GOST R 54934-2012 (OHSAS 18001:2007), GOST (ISO 14001:2004).

CR steel strip as per GOST 2284-79 is produced at the slitting line No1. of steel strip shop and at the slitting line No.2 of steel profile shop.

Testing methods

Tests are carried out at supplier’s place on samples in accordance with the following table:

Other nondestructive and destructive tests can be carried out on customer’s requirement.

Surface quality.

Bright strip can be of different shades of zinc color. Exact color of dark strip is not regulated. Roughness quality of bright strip is not more than 1,25 Ra.

Blister, scale, corrosion, tears, rolled-in particles and other defects are not allowed.

UMC LLC produces CR steel strip as per GOST 2284-79 of following sizes:

As may be agreed, strips can be produced of sizes not mentioned in GOST 16523-97, ranging from 0,25 to 3,0 thickness and from 9 to 1500 width.

CR steel strip GOST 16523-97 is produced of steel of the following grades:

1) 15, 15ps, 20, 20ps, 25, 30, 35, 40, 45, 50, 55, 60, as per GOST 1050-2013;
2) 65, 70 as per GOST 14959-79;
3) 18ua as per GOST 803-81.

Mechanical properties of CR strip GOST 2284-79 depend on the material state.

С целью обеспечения более эффективного раскроя горячекатаного и холоднокатаного рулонного проката производится лента стальная (штрипс). Данный вид продукции получают двумя способами: прокаткой или продольной резкой листовой рулонной стали. Изготовление ленты холоднокатаной основано преимущественно на резке, поскольку на такой вид ленты цена ниже и желающих купить ее гораздо больше. Лента холоднокатаная по ГОСТ может выпускаться нагартованной, мягкой, нормальной точности и т.д. Цена на ленту определяется исходя из рыночной стоимости на горячекатаный и холоднокатаный прокат.

Область применения

Горячекатаная и холоднокатаная стальная лента находит применение в следующих сферах:
Штрипс горячекатаный используется для производства труб – электросварных и профильных. Лента хомутная, используемая для стяжки труб, также изготавливается из штрипса.
Стальная лента активно используется для производства продукции для строительства. В частности, штрипс для профиля, производство профильных труб +из штрипса
Лента стальная электротехническая для бронирования кабеля может поставляться оцинкованной, неоцинкованной, нормальной или повышенной точности.
Пружинная холоднокатаная лента производства УМК используется при производстве пружин и инструментов. Более мягкий рулонный штрипс (гибкая стальная лента) используется для штамповки деталей машин и оборудования.
Производство ленты холоднокатаной в значительной мере ориентировано на изготовление упаковочных, обвязочных и бандажных материалов. Обвязка стальной лентой осуществляется специальным оборудованием и инструментами, купить которые можно в нашей компании (подробнее см. «Упаковочный инструмент»).
