Cold-rolled ribbed steel Environmental requirements: steel test is generally within the temperature range of 10 ~ 35 ℃ conduct, there are strict requirements of the test, the temperature was 23 ± 5 ℃. Determination of tensile strength Rm: Look steel surface quality, reinforcement should be no harmful surface defects. Buying original gauge marks 6.5mm cold-rolled strip steel straight, the application of small marks, fine lines crossed or ink marking gauge, but not with the cause of premature rupture of the notch mark. The ratio of the sample 6.5mm cold-rolled steel straight cash, calculate the value of the original gauge rounded to the nearest multiple of 5mm, the middle value to the larger party rounding. The original gauge length shall be marked accurately to ± 1%. Cold-rolled ribbed steel construction elements: cold-rolled ribbed steel installation. Cold-rolled ribbed steel welded joints connecting non-lap lap joints connecting segments within the same area should not exceed 25%. Ligament installation forming non Exalted stampede or heavy heap pressure straight 6.5mm cold-rolled steel prices to avoid a straight cold-deformed rebar, plate negative reinforcement every aspect lm applications support high horse stool tendons, concreting route erection sidewalk should avoid excessive deformation reinforced. 6.5mm cold-rolled strip steel production plant straight, Ding Ding cold-rolled, cold-rolled straight rebar Henan provided by Ding Ding Industrial Co., Ltd., Henan Province. Ding Ding Industrial Co., Ltd., Henan Province (www.hnddsy.com) is Anyang, other leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
