THE PAG-ASA REBAR [Top]
Pag-asa Steel rebar products are identifiable through the Company Logo ("PSW", short for Pag-asa Steel Works), which is hot-rolled and embossed onto each bar at specified intervals. The Rebar Size Mark, which specifies the nominal diameter of the bar, is also hot-rolled adjacent to the company logo.
Pag-asa Steel pioneered the practice of placing its logo on its bars in 1975, before it was mandated by law. The Bureau of Product Standards of the Department of Trade and Industry of the Philippines now requires all rebar manufacturers to put identifying marks on their bars.
Pag-asa Steel produces superior reinforcing steel bars in an array of sizes, lengths, and grades in adherence to Philippine National Standard (PNS 49:2002), as well as the global ASTM Standard (ASTM A615/A706) established by the American Society for Testing and Materials (now known as ASTM International).
BAR SIZES [Top]
Pag-asa Steel manufactures and sells the following standard sizes (in nominal diameters): 10mm, 12mm, 16mm, 20mm, 25mm, 28mm, 32mm, and 36mm. Larger sizes such as 40mm and 50mm bars may be produced via special order.
For steel bars, the terms "size" and "nominal diameter" are used interchangeably.
WEIGHT TOLERANCE [Top]
Because variation in cross sectional area occurs during hot rolling, a corresponding variation in linear weight is to be expected. For this reason, PNS 49 provides for an allowable 'variation in mass' (VIM) of ±6%, measured using one meter of rebar.
COMMERCIAL LENGTHS [Top]
Pag-asa Steel rebars come in the following commercial lengths: 6.0m, 7.5m, 9.0m, 10.5m, and 12.0 m. Special lengths of 13.5 and 15.0 meters may be produced via special order.
Just like weight, the cut length of a rebar may also vary because of shrinkage as it cools down. The minimum acceptable lengths of the finished rebar according to the Philippine Standard are as follows:
|Std. Length (m)||Min. Acceptable Length (m)|
Pag-asa Steel rebars comes in the following grades to meet high, intermediate, and low-tensile building requirements.
|ASTM vs PNS Codes||Popular Nomenclature||Typical Application|
Grade 33 / PNS 230
Low-rise Buildings and Low Loading Conditions
Grade 40 / PNS 275
Medium-rise Structures / Infrastructure Work
Grade 60 / PNS 415
Medium & High-rise Structures / Infrastructure
Higher tensile grades designated as Grade 75 / 500 and Grade 80 / 550 are also available subject to agreement and availability.
The three grades are distinguished by different color markings painted at the ends of each bar, as shown in the following table:
