Introduction
This report is to present the finding of my visit to SMI facility in Umm Al-
Quawain and technical assessment of their deck profiles.

GETS – February 5, 2020 Page 2 of 9

Machinery
They have a Chinese rolling lines (two) to produce two deck profiles 54 & 76
mm deep using material 345 grade in thickness range of 0.74 to 1.50 mm

Profiles
The following is their profiles

GETS – February 5, 2020 Page 3 of 9

Canam vs SMI
SMI profiles are mostly equivalent to Canam profiles 3603 & 2432.

UL Certification
SMI profiles are UL certified.

GETS – February 5, 2020 Page 4 of 9

Rolling Lines
These are two lines (one for each profile) manufactured by
HANGANGZHOU JINGJING – China

………

GETS – February 5, 2020 Page 5 of 9

Conclusion
SMI Composite Deck can be used by ZS from technical point of view.
Also, commercially it’s slightly cheaper. As per Mandeep, the price for 0.74
mm is in the range of DHs 32-34 per m2 against +/- SR 100/m2
discountable for Canam.

exceed the scope of the tables, the diaphragm shear
may be determined in accordance with the provision
of ACI 318 and AISC 360-10 as follows.

a. The diaphragm shear shall be the lesser of

the capacity of the reinforced concrete and the
capacity of the welded shear studs to transfer
the shear from the supporting member to the

1. Horizontal and vertical Deflection is limited to 6 mm maximum for concrete dead load

2. Design stress is limited to 138 mpa for concrete dead load temporarily increased by one-third for the construction live load of 1 kpa
3. Pour Stop Selection Table does not consider the effect of the performance, Deflection, or rotation of the pour stop support which may
include both the supporting composite deck and/or the frame.
4. Vertical leg return lip is recommended for type 16 and lighter.
5. This selection is not meant to replace the judgement of experienced Structural Engineers and shall be considered as a reference only.
