Core Products Support Margins: COG's margins for its H-section
steel products were resilient despite pressure on selling prices arising from industry-wide production overcapacity.
In all cases, the H-section considered is inscribed in a rectangle with a ratio c/b = 2 (see Figure 2), being a section widely used in civil construction as in the case of some bridge decks or as vertical suspension bars.
The absence of gallop for large porosities, say, greater than [phi] = 0.4, can be explained by the fact that the central core of the H-section, without the vertical plates, is a rectangular section with h/c = 0.25 (see Figure 2) which as reported elsewhere is not prone to gallop [4, 21].
Figure 9 shows the root mean square (rms) of the maxima of the dimensionless vertical amplitude, z/b, where z stands for the vertical amplitude and b for the frontal height of the H-section beam, as a function of the reduced velocity, [U.sub.red] = [U.sub.[infinity]]/([omega]b), for zero angle of attack.
where [[empty set].sub.c] is the resistance factor (0.9 for H-section and 0.75 for CCFT) and [P.sub.n] denotes the nominal compressive strength.
The maximum diagonal dimension of the H-section in Table 2, including shear studs, is 669 mm because headed studs are typically welded to an H-shaped column in a workshop and then delivered to the field.
The "stable" outlook mirrors Fitch's projection that the company's solid market standing in the H-section
products and constant optimisation of its product mix offsets the risk stemming from the intensely competitive Chinese steel market, the agency said.
Making stained glass involves using coloured glass and lead-came (the H-section
that holds glass pieces in position).
I do not know who constructed the statue but apart from the very substantial metal base plate the statue was made of flimsy materials, an undersize H-section
girder with light metal tubing and chicken pen wire netting covered in fibre glass.
"Through expanding its production capacity to over 10 million tonnes per year (mtpa), it is now being recognised as a tier-1 steel producer in Hebei province and a leading H-section steel producer," Lim added.
The "stable" outlook is based on Fitch's projection that the company's strong market standing in H-section products and improved outlook for its cold-rolled products will mitigate margin weakness caused by high raw material costs and intense competition for its basic steel products.
