Square Ductile Gratings are a type of grating system that is commonly used in various industries and applications. These gratings are designed to provide a strong and durable solution for platforms, walkways, and other areas where heavy loads and frequent foot traffic are expected. In this article, we will explore the characteristics, features, and benefits of square ductile gratings in detail.
In addition to their strength and durability, square ductile gratings also offer several other benefits. One of the main advantages is their ease of installation. These gratings are often supplied in pre-fabricated panels, which can be quickly and easily installed using standard fixing method.
In conclusion, square ductile gratings are a reliable and robust solution for various industrial and commercial applications. Their ductile iron construction provides strength, durability, and resistance to impact and corrosion. The square-shaped openings allow for efficient drainage and airflow, while also providing a stable and secure surface. With their ease of installation and low maintenance requirements, square ductile gratings offer a cost-effective and versatile solution for many industries.

Square ductile gratings are typically made from ductile iron, a type of cast iron that has been treated with a small amount of magnesium to enhance its strength and toughness. This material is known for its high resistance to impact, fatigue, and corrosion, making it ideal for outdoor and industrial environments. The ductile iron construction also allows for a higher load-bearing capacity compared to other materials, such as steel or aluminum.
One of the key features of square ductile gratings is their square-shaped openings. These openings are designed to allow for the efficient drainage of water, debris, and other materials, reducing the risk of slips and falls. The square shape also provides a stable and secure surface for walking or standing, even in wet or slippery conditions. Additionally, the openings allow for ample airflow, which can be beneficial in applications where ventilation is required.
Square ductile gratings are available in a variety of sizes and load ratings to suit different requirements. The load rating refers to the maximum weight that the grating can safely support without deformation or failure. This makes it crucial to choose the appropriate load rating based on the expected load and usage of the grating. Higher load ratings are typically achieved by increasing the thickness and depth of the grating bars.
Square ductile gratings are also highly versatile and can be used in a wide range of applications. They are commonly used in industrial settings, such as oil refineries, chemical plants, and power stations, where heavy loads and harsh conditions are present. They are also suitable for commercial applications, such as pedestrian walkways, ramps, and platforms. The strong and durable nature of these gratings makes them ideal for areas with high foot traffic, such as airports, train stations, and shopping centers.
Egg futures return to the rising glass, plummeting over 2%
On the 20th, the overall market trend showed more divergence. Agricultural products saw a recovery in egg futures, while soybeans and oysters were strongly influenced by the National Reserve auction and rising pork prices. Meanwhile, glass futures fell by over 2%, and base metals saw narrowed gains. Analysts noted that concerns about the real estate sector's weak outlook are weighing on demand for industrial products like glass, leading to continued pressure on these sectors in the short term.
On Tuesday, glass futures faced a sharp decline. The main 140 contract closed at 1,158 yuan/ton, hitting a new low and falling 28 yuan or 2.36%. Data revealed that both the new housing construction area and commercial housing sales in China have declined year-on-year this year. In March, the new housing construction area dropped 25.2%, and commercial housing sales fell 3.8%. This significant drop in new housing starts has severely impacted glass demand.
Looking at specific commodity trends, with the Dragon Boat Festival approaching, market sentiment was strong. In addition to lingering bird flu effects, tight egg supplies supported a rebound in futures prices. At the close, the main 1409 contract of eggs ended at 5,266 yuan per 500 kg, rising 84 yuan or 1.52%.
Shanghai copper saw a slight rise, with the main 1408 contract closing at 48,810 yuan/ton, up 190 yuan/ton. While the copper plate rallied slightly today, gains were limited. Fundamentally, the northern hemisphere is in its peak season for traditional manufacturing, which supports copper demand. However, attention is now on the Fed’s April meeting minutes and China’s May HSBC manufacturing PMI. Market expectations are neutral, so caution is advised regarding copper price rebounds. In the short term, Shanghai copper may continue its overall upward trend.
Aluminum futures saw narrower gains, with the main 1407 contract closing at 13,125 yuan/ton, up 15 yuan/ton. Recently, Shanghai Aluminum has risen passively along with surrounding basic metals, but it faces stronger selling pressure. The current spot price is stagflation compared to the futures price, with the discount gradually widening. Given high output levels, the gains in aluminum futures remain limited.
Dalian palm oil futures adjusted lower, with the main 1409 contract closing at 5,900 yuan/ton, down 54 yuan. Overnight oil prices fell, putting pressure on the domestic oil market. Malaysian palm oil exports in the first 20 days of the month were slightly lower than expected, and China’s imports have decreased, signaling weaker demand and pressuring the market. Since March, domestic palm oil imports have declined, and demand has picked up slowly, with port inventories remaining high. Short-term adjustments are still needed for palm oil.
Soybean oil futures continued to fall, with the main 1409 contract closing at 6,764 yuan/ton, down 30 yuan. Falling overnight oil prices pressured the domestic soybean oil market. However, due to the release of the National Reserve Soybean auction and today’s Malaysian palm oil export data, the market remained in a wait-and-see mood, which limited the downward movement. In the short to medium term, the contradiction between domestic supply and demand for oils has become more pronounced, and the pattern of “strong oil but weak prices†is expected to continue, leaving downside risks for soybean oil prices.
