How Should You Choose Zinc Ingots?
Zinc ingots are metallic materials cast from primary metallic zinc. Trace impurity elements may remain during smelting, yet metallic zinc constitutes the principal component. Impurities including lead, cadmium, iron, copper, tin and aluminum can affect the mechanical pr...Read more -
How to Choose Color-Coated Coils?
Color coated coils are manufactured using cold rolled steel sheet or galvanized steel sheets as the base material, and are processed through a series of steps including continuous surface pretreatment, baking, and cooling. The product offers advantages such as being po...Read more -
What is the difference between square tube and square bar?
Square bar refers to a square-shaped material produced by hot-rolling square billets, or by cold-drawing round steel. Theoretical Weight Formula: side length × side length × 0.00785 = kg/m. Square tubing refers to a tubular shape with a square cross-section. It...Read more -
What is the difference between round bars and deformed rebar?
In construction, there are many types of steel commonly used, among which round bars and rebar are the most prevalent. The main differences between them are as follows. Today, we’ll briefly discuss these differences. Round Bars (HPB Series) The surface of round bars...Read more -
Why Can Galvanized Steel Pipes Resist Corrosion for Decades?
Rusting is an inescapable fate for steel products. However, galvanized steel pipes are an exception — they can withstand harsh environments such as humidity and acid rain for decades without deteriorating. The secret behind this lies not in the steel pipe itself, but i...Read more -
Heat Treatment in Steel Processing—Annealing
In the processing and heat treatment of steel, annealing, normalizing, quenching, and tempering are four fundamental yet critical heat treatment processes. By controlling the heating temperature, holding time, and cooling rate, these processes alter the internal microst...Read more -
Practical Calculation Methods for scaffolding Budgets
Calculation Rules (1) When calculating scaffolding for interior and exterior walls, the areas occupied by door and window openings, ring openings, and similar features shall not be deducted. (2) When a building has sections of varying heights, calculations shall be perf...Read more -
What are the types and specifications of adjustable steel bracing structures?
Adjustable steel props consist of several components: inner tubes, outer tube connectors, pin plates, T-shaped threaded rods, top supports, U-bolts, and die-cast nut sleeves. The features of adjustable steel props include: 1. High load-bearing capacity and high construct...Read more -
What inspections are performed on steel products before shipment? What tools are used for testing?
Most steel processing involves pressure processing, which causes the steel being processed (such as billets or ingots) to undergo plastic deformation. Depending on the processing temperature, this can be divided into two types: cold working and hot working. Steel...Read more -
What Do Buyers of Die-Cast Zinc Alloys Want to Know Most?
I Characteristics of Zinc Alloys Key Properties: High density. Good casting properties; capable of producing complex, thin-walled precision parts with smooth surfaces. Suitable for surface treatments: electroplating, powder coating, and p...Read more -
What is the difference between GB/T 470-2008 and GB/T 13818-2024?
Although GB/T 470-2008 and GB/T 13818-2024 both appear to be related to zinc, their actual application scenarios and product types are entirely different. The core differences primarily lie in the scope of application, the products themselves, and specific technical re...Read more -
What are the differences and similarities between unequal-leg angle steel and equal-leg angle steel?
Galvanized angle steel has two sides of equal length, forming a perfectly symmetrical right-angle structure. A common specification, such as ∠50×50×5, indicates that both sides are 50 mm wide and 5 mm thick. Due to its regular shape and uniform stress distribution, it ...Read more
