Steel Grating
The steel grating be welded to products . Normally, hot galvanizing will be carried out after end welding process. The range PH6 to PH12.5, a stable protective film will be formed on the zinc surface, the hot dipped galvanized steel grating has good anti-corrosive property. Of course, the steel grating also have other surface treatment, for example painted and powder coated .
Steel grating can be cutting to different kinds of shape as per your special needs.
Steel grating including flat grating, 'I' shape grating, serrated grating.
In generally , the steel grating be used as stair tread, platform, fence, trench cover, ceiling, etc.
The advantage of steel grating :
firm welding
smooth surface
high strength

High-yield cultivation techniques of black sesame
There are many varieties of black sesame, and the first selected variety is Zhongshi No. 9 which was selected for the research of oil crops in the Chinese Academy of Agricultural Sciences. The variety is branched and the yield per mu is up to 58.33 kg. Summer breeding period 95 days. The seed coat is black and the grain weight is 2.63 grams. Oil content of 47.3%, protein content of 21%. This variety is resistant to stem blight and is worth promoting. At present, sesame seeds are grown mainly using the "double stem cultivation method." The method mainly removes the tip when the third pair of true sesame seedlings is unfolded, so that the first (or second) pair of true leaf axillary buds grows to form a double stem. Use this method to grasp the following points: 1, drug dressing seedlings for cropping, grabbing and sowing before sowing can be used before sowing 50% carbendazim WP or 40% carbendazim glue suspension 8 grams, add water 0.5 kg adjustment Mix into a paste with 0.5 kg of seed and wait for the broadcast. Sesame bogey is heavy and it advocates 4 years for 2 systems. It is to grab a good mouthful and sow early. 2, suitable for early sowing to grasp the density of summer sesame seeding period not later than June 15, generally as early as possible. Cultivation density is generally 667 m2 8000--10000 strains is appropriate. 3. Strictly control the time and methods of topping. Summer sesame seeds retain 2 pairs of true leaves topping, and retain stem segments above leaves of 2--3 cm. In the same field, the standard of preserved leaves is the same, and the one-time summit is completed. 4. Pay attention to supplementing and catching Miaofei sesame topping. In order to prevent de-fertilization of new-born shoots, appropriate amount of quick-acting fertilizer may be applied. When new-born shoots grow on the second and third pair of true leaves, they should be sprayed 100 times. Amine or oxazole to prevent late lodging and increase the number of effective pods. 5, anti-smear early morning early tube to prevent grassland planting when the first to open a good ditch and ditch, generally 2 to 2.5 meters wide, ditch depth of 0.3 meters, ditch depth of 0.4 - 0.5 meters. The gully setting depends on the topography and soil quality, and the average ditch should be made well. Seedlings grow 2--3 pairs of true leaves when the Dingmiao, row spacing is 36 cm 12--15 cm, and weeding 1 times. When the seedling height is 33 cm, the soil is combined with top dressing. 6, scientific fertilization to prevent pests due to short summer sesame seedlings, the need for more fertilizer and concentrated, should apply the main base fertilizer. Apply about 15 kg of ammonium per acre, add 30--40 kg of phosphate, and 6--8 kg of potash. In the growing season, the thin, weak growing plots can be topped with 3--5 kg ​​urea per acre. In the jointing stage, anti-angle blight and leaf blight can be used to spray the leaves twice with 50% fluocin and 1,000 times liquid. Such as aphids occur 2000--3000 times Dimethoate mist.
