How to access the Material Type of the physical Asset

[Anonymous]

Hello, I am filtering all the materials and I want to sort them by the Type property that belongs to the Physical Asset. Up to now, I have tried the following:

ElementId materialId = keyMaterialId;
Element e = m_doc.GetElement(materialId);
Parameter paramMaterial = e.get_Parameter(BuiltInParameter.STRUCTURAL_MATERIAL_PARAM);
Material material = m_doc.GetElement(materialId) as Material;

                if (material.StructuralAssetId != 
                    ElementId.InvalidElementId)
                {
                    PropertySetElement property = 
                    m_doc.GetElement(material.StructuralAssetId) as 
                    PropertySetElement;

                    Parameter paramType = 
 property.get_Parameter(BuiltInParameter.PHY_MATERIAL_PARAM_TYPE);
                    if (paramType != null)
                        Debug.WriteLine("material " + 
                         paramType.AsValueString());
                }

The code gets into the first if, so that means that it correctly gets the Physical Asset, but when I try to get the Type (in the variable paramType), paramType is always null, I know this because it never does the Debug.Writeline();

Any ideas?
