La especificación artículos de primera necesidad de los deformes acero bar tengo que ser designada en la importacion y exportacion cambiar contrato. Generalmente, debería abarcar el bien conocido grado (código de tipo), el diámetro nominal del metal barra, el peso nominal (masa), la preciso longitud y la tolerancia costo de los indicadores anteriores, etc.
de nuestro pais requisitos aconsejar deformado metal bar secuencia con diámetros nominales de 6, 8, 10, 12, 16, 20, 25, 32, 40 y 50 mm. El tamaño de conceder se divide en dos tipos: constante tamaño y doble longitud. El constante tamaño determinación variar de las exportaciones de mi país deformadas metal barras es de 6 a 12 m, y el constante tamaño elección variar de japoneses deformes metal barras es de 3,5 a 10 m. Si no hay ningún requisito designada en el contrato de hogar hogar deformado metal bares, el constante tamaño es típicamente 9m y 12m.
Dimensions & Appearance
1) Nominal diameter vary and encouraged diameter
The nominal diameter vary of metal bars is 6 to 50mm, and the preferred encouraged nominal diameters of metal bars are 6, 8, 10, 12, 14, 16, 20, 25, 32, 40, and 50mm.
2) Permissible deviations in floor structure and dimension of ribbed metal bars
The plan standards of ribbed metal bar transverse ribs need to comply with the following regulations:
The attitude β between the transverse rib and the axis of the metal bar must no longer be much less than forty five degrees. When the perspective is now not larger than 70 degrees, the instructions of the transverse ribs on the contrary facets of the metal bar need to be opposite;
The nominal spacing l of transverse ribs shall now not be increased than 0.7 instances the nominal diameter of the metal bar;
The perspective α between the aspect of the transverse rib and the floor of the metal bar shall now not be much less than forty five degrees;
The whole hole (including the width of the longitudinal ribs) between the ends of the transverse ribs on two adjoining surfaces of the metal bar need to now not be increased than 20% of the nominal circumference of the metal bar;
When the nominal diameter of the metal bar is now not higher than 12mm, the relative rib region ought to now not be much less than 0.055; when the nominal diameter is 14mm and 16mm, the relative rib vicinity need to now not be much less than 0.060; when the nominal diameter is higher than 16mm, the relative rib region have to now not be much less than 0.065. For the calculation of the relative rib area, please refer to Appendix C.
Ribbed metal bars commonly have longitudinal ribs or may additionally no longer have longitudinal ribs;
3) Length and allowable deviation
a. Length
Steel bars are normally delivered in constant lengths, and the particular shipping size have to be designated in the contract;
Steel bars can be delivered in coils, and every coil ought to be one metal bar. It is allowed that 5% of the wide variety of coils in each batch (two coils if much less than two coils) are composed of two metal bars. The disc weight and disc diameter are decided by way of negotiation between the grant and demand parties.
b. Length tolerance
The allowable size deviation of metal bars when delivered to constant size shall now not be larger than ±25mm;
When the minimal size is required, the deviation is +50mm;
When the most size is required, the deviation is -50mm.
c. Curvature and ends
The ends of the metal bars need to be sheared straight, and nearby deformation have to now not have an effect on use.
Application
Deformed metal bar is extensively used in the development of houses, bridges, roads, and different civil engineering projects. From public amenities such as highways, railways, bridges, culverts, tunnels, flood control, and dams to the foundations, beams, columns, walls, and plates of residence construction, the deformed metal bar is an fundamental structural material. As China's urbanization continues to deepen, the booming improvement of infrastructure building and actual property has created a robust demand for deformed metal bars.
