STEEL SPECIFICATIONS

SPECIFICATION for 1.1 mm Steel

UBM ®-120 SYSTEM STEEL COIL SPECIFICATIONS - Note that the UBM 120 will be used for all 1.1mm steel

PRODUCT: Galvanized steel in coils conforming to ASTM A653-05, structural quality (SS), suitable for roll forming, pre-painted (as specified below) recommended, minimum base material to be AISI 1018, preferably use AISI 1020 minimum elongation is to be 22%, 25-30% is ideal hardness range shall be 70-78 Rb.

COIL WIDTH: 23.5 inches to 24 inches (optimum is 23.75 inches) 59.69 cm to 60.96 cm (optimum is 60.325 cm). This width is for the UBM 120 panel only (order thickness is 1.1mm)

COIL DIAMETER: Maximum outside diameter: 40 inches (101.6 cm) Inside diameter: 19 to 21 inches (48.25 cm - 53.35 cm)

COIL WEIGHT: Maximum: 5,000 lbs. (2,268 kg)

STEEL GRADE: Grade 50 Class 1: Yield Strength 50,000 psi or 3,500 kg/cm2 or 35 kg/mm2.

THICKNESS: 1.1mm (with a maximum thickness of 1.20mm or a maximum tolerance of +0.10mm)

TOLERANCE: NO NEGATIVE TOLERANCE IS ACCEPTABLE. NO POSITIVE TOLERANCE GREATER THAN 0.10mm

GALVANIZED COATING: Class G-60 (Z-180) can be used for pre-painted although G-90 (Z-275) is preferred Regular spangle, chemical treated, lightly oil with evaporative lubricant for galvanized only coils.

GENERAL PAINT SPECIFICATIONS: RAL1014 MUST BE USED. Comply with the paint specification. Failure to comply may cause paint to be damaged during the bending process. Coating topside - Suitable for roll forming, 25 microns total dry thickness, polyester, with internal lubricants, on primer. NCCA Standard "T" bend Test method or ASTM D4145-83 (must pass 2T bend test,

no pick off with Scotch #610 tape). ECCA test to 1T is also acceptable. Coating test to ECCA T1 at every coil. Light wax or evaporative lubricant to be applied to exterior of paint.

Backside - 12 microns total dry thickness, epoxy primer, and polyester wash coat.

SPECIFICATION FOR 1.52 mm Steel

ABM ®-240 SYSTEM STEEL COIL SPECIFICATIONS -Note that the ABM 240 will be used for all 1.52mm steel
