COATING MASS STANDARD (SNI 07-2053-2006)


keterangan:
1. The average coating mass in the triple-spot test on both surfaces shall be the average of measured coatings masses of the three piecces cut from the test specimen.
2. The minimum coating mass at single spot on both surfaces shall be the smallest of the measured coating masses of three pieces cut from the test specimen.
3. The maximum coating mass on both surfaces may be agreed upon between the purchaser and manufacturer.

COATING MASS CLASS (SNI 07-2053-2006)

CLASSIFICATION and DESIGNATION

Note:
Equiry for a grade and nominal thickness other than the above, maybe produced based on the purchaser and the manufacturer agreement.

MECHANICAL PROPERTIES (JIS G 3302)

a.Hot Rolled Base Metal

Note :
For grade SGHC, the yield point and tensile strength are normally at least 205 N/mm2 and 270 N/mm2 respectively.

b.Cold Rolled Base Metal

Note :

  1. When non-aging property for the sheet and coil of SGCD3 is required, this property shall be guarantedfor the period of 6 months.
  2. For nominal thickness less than 0.25mm, tension test shall not, as a rule, be conducted.
  3. For grade SGCC, the yield point and tensile strength are normally at minimum 205 N/mm2 and 270 N/mm2 respectively.
  4. SGCH material are not subjected to annealing, usually having Rockwell Hardness (HRB) of 85 or more or a Vicker Hardness (VH) 170 or more. (The test load may be chosen appropriately).

STORAGE

SUPER LOKFOM GALVANIZED STORAGE

Sheets/coils have to be stored in a dry place (not humid), with good air circulationand protected from rain, wate spill, corrosive chemical, dew, ground, and other dirt.
If there is wet surface during storage, sheets/coils should be dried first before they put in storage.
Sheets/coils have to be covered with tarpaulin or other water proof material.There should be a gap between cover and   sheets/coils to allow air circulation.
Direct contact to earth, floor, dirt, waste, and water spill are not allowed.
During storage/usage/transportation, friction between sheets/coils should be avoided, because sharp edges of the sheets/coils can cause scratches to the surface of the other  sheets/coils.
Aviod water accumulation between sheets/coils.It causes water stains on the surface, called water defect.

SENG LOKFOM BJLS

Plat seng Lokfom atau biasa di sebut dengan BJLS yang banyak di gunakan untuk talang, cover ducting dan lain – lain mempunyai ukuran dan ketebalalan yang beragam sesuai dengan kebutuhannya.

LOKFOM

Pada dunia industri ada yang bilang Lokfom dan BJLS (Baja Lapis Seng). Rata – rata produk ini menggunakan tebal di atas lebih dari 0,3 mm, sehingga sulit untuk membendingnya / membengkokannya dengan tangan, banyak yang menggunakan dengan jasa mesin untuk membending.

Ukuran dan Ketebalan Plat Seng Lokfom BJLS

Spangle/kembang dari permukaan lapisan seng merupakan hasil pengkristalan zinc secara normal, dengan bentuk yang homogen dan mengkilap, Tebal 0,2 s.d. 3,8 mm. Tipe lapisan ini sangat cocok untuk penggunaan atau pemakaian secara umum.

SENG LOKFOM

Lokfom / BJLS ini terbagi dalam 2 jenis, ada yang di jual lembaran maupun ada juga yang gulungan, Inilah Ukuran dan Ketebalan Plate Seng Lokfom BJLS berikut spesifikasinya :
