Performance 1: The process flow is fine, the surface treatment is smoother, and there will be no traces on the welded parts. As can be seen, this is technically more refined and better in quality. Grasp the strict technological process, the quality level of processing will be higher, so as to achieve a higher standard in the process of sales in the market.
Performance 2: Strict process testing standards. Since the steel grating has strict reference standards in each process of processing, the purpose is to have more inspection points in all aspects. Therefore, as long as the process is stricter and the factory effect is good, the trust of customers will be higher in the process of marketing. Especially when installed on uneven platforms, no leakage will occur.
Performance 3: High acid and alkali resistance. No matter what kind of special environment the steel grating is installed and used in, there will be no corrosion or damage for many years. It can be seen that this is also a higher standard in terms of standards, and every technical detail in the processing process will be more considered. In this way, it can be sold in the market, gain the trust and recognition of customers, and improve the sales advantage in the market.
The steel grating is tested before leaving the factory. Next, we will explain in detail the testing requirements and steps of the steel grating. Test requirements: The three parts where the sample is in contact with the testing machine should be flat and have good contact with each load-bearing flat steel, and the sample processing should be flat.
1. The length of the sample is 680 mm, the distance between the support rollers is 600 mm, the length of the sample is 1 1 50 mm, and the distance between the support rollers is 1 000 mm. The length of the support roll should be greater than the width of the sample.
2. Apply the load to the middle of the sample perpendicular to the direction of the bearing flat steel with the zigzag indentation of the testing machine. The length of the zigzag indentation should be greater than the width of the sample. Before loading, make sure the backup rollers and dimples have good contact with each bearing flat.
3. Measure the zigzag deflection of the sample with a dial gauge. Dynamometer readings are recorded and actively recorded. The instrument plots a load deflection curve from the recorded dynamometer readings. Factors of shock and fatigue should also be considered when planning steel gratings for use on traffic roads. The numerical calculation of the load table is carried out according to the nominal scale of the bearing flat steel. If the bearing flat steel has a negative tolerance, a reduction factor should be considered. Samples, load-bearing flat steel should take into account the changes in the cross-sectional scale due to punching, opening and notching.
