Lithopone is added to plastic resin systems to enhance UV protection of the final plastic products that includes outdoor plastics and automotive plastics. It is used as a white pigment for plastics such as polyolefin, vinyl resin, ABS resin, polystyrene, polycarbonate, nylon, and polyoxymethylene (POM). It ensures that UV rays do not penetrate and damage the product and its appearance.
The skin of an adult person is, in most places, covered with a relatively thick (∼10 μm) barrier of keratinised dead cells. One of the main questions is still whether TiO2 NPs are able to penetrate into the deeper layers of the skin. The majority of studies suggest that TiO2 NPs, neither uncoated nor coated (SiO2, Al2O3 and SiO2/Al2O3) of different crystalline structures, penetrate normal animal or human skin. However, in most of these studies the exposures were short term (up to 48 h); only few long-term or repeated exposure studies have been published. Wu et al.83 have shown that dermal application of nano-TiO2 of different crystal structures and sizes (4–90 nm) to pig ears for 30 days did not result in penetration of NPs beyond deep epidermis. On the other hand, in the same study the authors reported dermal penetration of TiO2 NPs with subsequent appearance of lesions in multiple organs in hairless mice, that were dermal exposed to nano-TiO2 for 60 days. However, the relevance of this study for human exposure is not conclusive because hairless mice skin has abnormal hair follicles, and mice stratum corneum has higher lipid content than human stratum corneum, which may contribute to different penetration. Recently Sadrieh et al. performed a 4 week dermal exposure to three different TiO2 particles (uncoated submicron-sized, uncoated nano-sized and coated nano-sized) in 5 % sunscreen formulation with minipigs. They found elevated titanium levels in epidermis, dermis and in inguinal lymph nodes, but not in precapsular and submandibular lymph nodes and in liver. With the energy dispersive X-ray spectrometry and transmission electron microscopy (TEM) analysis the authors confirmed presence of few TiO2 particles in dermis and calculated that uncoated nano-sized TiO2 particles observed in dermis represented only 0.00008 % of the total applied amount of TiO2 particles. Based on the same assumptions used by the authors in their calculations it can be calculated that the total number of particles applied was 1.8 × 1013 /cm2 and of these 1.4 x107/cm2 penetrated. The surface area of skin in humans is around 1.8 m2 and for sun protection the cream is applied over whole body, which would mean that 4 week usage of such cream with 5 % TiO2 would result in penetration of totally 2.6 × 1010 particles. Although Sadrieh et al.concluded that there was no significant penetration of TiO2 NPs through intact normal epidermis, the results are not completely confirmative.
さらに、スチールグレーティングのサイズを選定する際には、耐荷重能力や使用環境も考慮する必要があります。重量が大きい機械が通過する通路や、重いラックが設置される床などは、強度が求められます。そのため、厚さや格子の開口部のサイズも重要な要素です。格子の開口部が大きすぎると、小さな物体が落下する恐れがありますし、逆に小さすぎると、排水機能が妨げられる可能性があります。

One of the primary benefits of steel grid walkways is their exceptional durability. Unlike traditional flooring materials, such as wood or concrete, steel can withstand harsh weather conditions, heavy loads, and significant wear and tear. This resilience makes steel grid walkways especially suitable for environments like manufacturing plants, warehouses, and outdoor spaces where exposure to the elements is common. The ability of steel to resist corrosion when treated properly further extends the lifespan of these walkways, ensuring they remain functional and safe for years to come.
Galvanized grating has a wide range of applications across multiple industries. It is commonly used for flooring, walkways, platforms, and drainage covers. Its open design allows for effective water drainage, making it ideal for areas exposed to liquids, such as factories, food processing plants, and wastewater treatment facilities. Additionally, due to its resistance to corrosion, galvanized grating is suitable for outdoor applications where it may be exposed to harsh weather conditions.
Moreover, it is frequently used in residential applications, particularly in outdoor spaces such as patios or garden walkways, where its drainage properties can significantly improve the usability of the area during rainy weather.

The weight of serrated grating can vary significantly based on several factors, including the material used, the thickness of the grating, and the design specifics such as the spacing between the serrations. For instance, stainless steel gratings are typically heavier than their aluminum counterparts due to the difference in material density. A standard length of serrated grating might weigh anywhere from 20 to 60 pounds, depending on these specifications.
Durability.
The protective coating applied to the steel grating not only enhances its aesthetic quality but also adds a significant layer of protection against corrosion and wear. The paint helps to shield the steel from environmental elements such as moisture and chemicals, which can be particularly damaging in industrial settings. Furthermore, the available colors and finishes allow for customization, enabling businesses and architects to align the appearance of the grating with the overall design of their projects.
The environmental aspects of heavy steel grating should not be overlooked either. Steel is a highly recyclable material, which means that grating products can contribute to sustainability efforts. As industries globally look to minimize their ecological footprint, using products like heavy steel grating aligns with green building practices and promotes responsible resource management.
Another noteworthy aspect of mesh grating flooring is its environmental impact. Manufacturers are increasingly focusing on creating products that are recyclable and sustainable. For instance, fiberglass mesh grating can be made from recycled materials, further reducing its ecological footprint.
