Why this time with the arrival of galvanized sheet volume of poor winter, at home yesterday's snow, the weather cool, galvanized sheet prices is in constant decline, the recent overall market galvanized sheet steel market price temporarily stable operation, market transactions in general. According to analysis of the steel market transactions and the market, a manufacturer of galvanized sheet prices are as follows: Baotou 1.0 * 1250 * C specifications galvanized offer 4720 yuan / ton, Steel 1.2 * 1250 * C specifications galvanized offer 4720 yuan / ton; Benxi 0.5 * 1000 * C specifications galvanized offer 4950 yuan / ton, Benxi 1.0 * 1000 * C specifications galvanized offer in 4720 yuan / ton; MCC Hengtong 0.5 * 1000 * C specifications galvanized offer in 4950 yuan / ton. Entire steel market due to poor demand, the major traders a lower volume, the market price of galvanized sheet in various regions of transient stability, traders gradually reflect the recent reduction in orders, lack of support force, a certain stock, although steel mills intend to pull market prices, but demand did not play a supporting, galvanized sheet prices weak, prices are still expected to post galvanized sheet running smoothly. 7, painted: base price does not move, now TSt01Z 0.5mm * 1200 * C color coated paper listed price of 5420 yuan / ton (tax 6341.4 yuan / ton), 100 0mm wide increase of 20 yuan / ton; 8, silicon steel: base price increase 700 yuan / ton, now M50W800 0.5mm * 1200 * C silicon steel volumes listed price of 6180 yuan / ton (tax 7230.6 yuan / ton); 9, the profile: the base price up 50 yuan / ton, Q235 5 # Angle listed price of 3200 yuan / ton (tax 3744 yuan / ton), Q235 16 # channel steel listed price of 3180 yuan / ton (tax 3720.8 yuan / ton); 10, H-shaped steel: the small size of H-shaped steel base price up 50 yuan / ton, Q235 200 * 200 H-beam specifications listed price of 3130 yuan / ton (tax 366 2.1 yuan / ton), Baosteel color steel, large size H-beam base price up 50 yuan / ton, Q235 300 * 300 specifications listed H-beam price of 3520 yuan / ton (tax 4118.4 yuan / ton). The above adjustments and involved prices are not included, since January 1, 2015 implementation date onwards. Two color-coated titanium coated with a 2-coat what the difference is positive 2-coat paint two two-layer (a primer layer of paint), paint the back of the back coating layer 2;? 2-coat paint one front layer 2 . (a primer layer of paint), paint the back of the back coating layer of two Tu two: should be two Tu two bake, two painted a color coating process is as follows: 1, pre-treatment: a clean, b of the coating 2 , a Tu: positive and negative painting and drying curing (a coating a bake) 3, 2-coat: positive and negative painting and drying curing (2-coat two baking, less demanding building materials board opposite unpainted) 4, three-coat: front painted and dried cured (three-coat three-bake, high-end appliances board) 5. Other: printing, coating (appliance panels, decorative panels) color-coated paint finish back how it was painted hardness enough? board lacquered hardness is not enough, always in S friction roller and paint, how to paint hardness increase back many reasons ah, ah, it is generally the following situations: 1, quality issues; 2, the baking temperature is not enough (not positive Diaoqi if these two unlikely); 3, back paint paint too thick; 4, paint formulations inappropriate, an appropriate increase in the crosslink density; the reason may be no topcoat. Paint coating process should be primed, apply finish. How to distinguish galvanized plate and electrolytic plate? Galvanized steel, the advantages of this steel is corrosion resistance is better. As you know, the steel is exposed to air more humid susceptible to corrosion, and galvanized steel can rely on a dense oxide protective layer of zinc metal in the air to protect the interior of steel. In the case of lacerations, relatively lively galvanized part can be used as a sacrificial anode delay steel corrosion, relatively thicker layer of galvanized steel more corrosion resistance is strong. Electrolytic galvanized steel plate and is divided into pyrolysis plate. Electrolytic plates are used in the vast majority of the chassis, in appearance, the color of this steel is gray. Electrolysis board has good corrosion resistance, but the cost is also relatively higher. Pyrolysis board looks very bright, the visual effect is very good, but the pyrolysis plate traditional manufacturing process has the disadvantage of corrosion may occur after a long time, although less expensive than electrolysis board, but still rarely used by the manufacturers. We usually say that galvanized sheet refers to the hot galvanized plate, and refers to the electrolysis board galvanized sheet (some would call it cold galvanized sheet), hot galvanized plate with galvanized sheet like that, Coating are zinc, the difference is not the same process, hot dip galvanized coating is generally thick, it can be used indoors and outdoors, depending on the thickness of the coating, electrolytic galvanized thin plate surface (flatness \ finish) than Redu zinc plate, galvanized sheet usually only for indoor use. zinc plating layer thinner than hot-dip galvanizing, but much to the passivation layer plating after. In addition, the hot-dip galvanizing basically strip, continuous galvanizing. Plating size is much smaller. Electrolysis board and galvanized sheet has been very vague, we used DVD hardware shell material in the end are still galvanized sheet electrolysis board ah first to find a concept and definition of galvanized sheet electrolysis board also called plating galvanized board SECC, there is a commonly used hot-dip galvanized steel SGCC, both galvanized sheet. SECC and SGCC appearance is very easy to distinguish, unless you have not seen these two common materials SECC generally uniform gray; SGCC white some common with large and small zinc spangle flower. Also whether there is information that spangle, but I have not seen, it is estimated that very few people use.
