Although some of the billets produced at Falcon Steel Mills are sold directly to customers, most are processed into bars in our rolling mills. We supply high quality steel billets of various cross-sections and sizes, which enable us to meet the customer requirements and industry specifications.

Permissible variations from specified ranges and marketing are tabulated.

1. LENGTH 3.8 meter to 12 meter (± 50mm) for 150 x 150mm² section)
6.0 meter to 12 meter (± 50mm) for 130 x 130 mm² section)
2. SECTION 150 x 150mm2 or 130 x 130mm2
3. FACE LENGHT ± 3mm
6. STRAIGHTNESS Camber 5mm/meter
7. BENDING Not more than 5mm in 1 meter
Not more than 30mm in 6 meter
Not more than 60mm in 12 meter
8. ANGULAR TWIST Not more than 1º / meter and
Not more than 6º over 12 meter length.
9. CUTTING Both ends will be Gas Cut
10. IDENTIFICATION At the end of each billet cast number will be stamped or written by paint
11. PIPE No Existence
The billets will be free from surface imperfections which impair the product quality such as longitudinal cracks, transverse cracks, Deep ripple mark, scab & thick scale, slag patches, surface blow holes & Internal quality should be free from harmful defects such as subsurface pinholes, blow hole, pipes, voids, and internal crack.

As Qatar Steel have open casting process, chances of minor surface pinholes is there and it will not impair the product quality.
