Factors and horizontal cross-sectional shape concrete WPC railing by the six control variables, which are lower slope width 4, bottom flange height S, down the slope height C, ramp width ? & gt ;, the ramp height E, top width F. By a combination of changes in these six variables to control the entire fence total width and total height. Therefore, these six variables as a factor orthogonal design. Reference NJ type straight railing size parameters, taking five levels for each variable studied, factor level. how much per linear foot to install vinyl fencing

According showed poor of each column are not equal, indicating the level of change in the degree of influence of various factors on the test results are not the same, the greater the poor, represents a number of factors that vary within the range of the test, the test will lead to index greater changes in value, so the level of poor biggest factors is a list of the biggest factors on the test results, which is the most important factor. pvc ceiling making Mexico

Thus, according to the primary and secondary factors affecting the degree of order results that is the extent of primary and secondary factors affecting the results as follows: ramp height & gt; bottom flange height; Gao degree slope; top width; width ramp; ramp width. Visible than the width of the impact height impacted significantly under the influence of slope Gao degrees and relatively high degree of influence on the slopes significantly.
